"Wow..., Wow...!" A swim sounded in the monkey's ears. The monkey turned his head and found Leng Xin swimming beside him. When he saw that Leng Xin had followed him, he even showed signs of surpassing him. The monkey's hands once again accelerated the swimming speed and wanted to swim in front of Leng Xin.

After all, the more monkey swims ahead, the less likely he is to be swallowed by the young sand tiger shark. When facing a desperate situation of life and death, Leng Xin's psychological deterrence to the monkey is no longer there.

Unfortunately, no matter how fast the monkey swims, it is useless. In less than five seconds, Leng Xin swam in front of the monkey.

The monkey's physical fitness is much worse than Leng Xin. Moreover, the monkey has lived in inland cities since childhood and has never swam much. Compared to Leng Xin, who grew up by the river since she was a child and has been soaking by the river in summer, his swimming skills are much worse, so soon, the monkey fell behind Leng Xin by five or six positions.

As soon as he saw that he was already in front and the monkeys closest to him had five or six positions, Leng Xin finally breathed a sigh of relief. The possibility of him being killed by the young sand tiger shark is the least.

However, although Leng Xin felt relieved, there was still a question in his heart that needed to be solved. Otherwise, Leng Xin knew that even if he escaped now, the final result would not be good. Only by solving this question in his heart could Leng Xin get out safely, and Leng Xin’s question in his heart is to distinguish the direction.

In the sea, distinguishing direction is the most important thing. Once you lose your direction in the sea, the final result..., no need to say. You also know what your final result will be.

In the vast ocean, the weather conditions are complex and changeable, and the clouds and sunny are uncertain, and many people will lose their direction. If you want to distinguish the direction in the ocean, you should learn more about astronomy knowledge and other common sense.

As long as we master these geographical and astronomy knowledge, we can distinguish directions based on the position of the sun, the positions of the stars (mainly the North Star), the wind direction, the direction of the sea water flow, and the compass.

Here are a few ways to distinguish directions in the sea.

The first type: cleverly use the watch to determine the position of the sun.

During the day, we can determine the direction based on the sun and watch. In fact, the watch is a "compass".

Look at how many numbers differ between the hour hand and 12 points, half of the number should be where the sun is.

For example, it is 8 am now, with 4 numbers apart at 12 o'clock, so half of 4 is the position of the sun, which should be around 10 o'clock; if it is 4 pm, the distance between 12 o'clock is also 4 numbers apart. Then half of 4, so the sun should be at 2 o'clock.

After mastering this, at 8 o'clock in the morning, lift your watch and face the sun at 10 o'clock, so the direction of 12 o'clock is almost south.

Another method requires sufficient time. When it is almost noon, you can see where the sun moves from in the sky to where it is within an hour. The direction pointed by this movement path is the east-west direction.

The second type: refer to the position of the stars (mainly the North Star). When there are stars at night, you can find the position of the North Star and bring a high-power telescope if possible. The effect is better. Finding the North Star can determine the specific direction of the sea, because you can see a bright star at the 5-fold extension of the mouth of the North Dipper. This star is the North Star, and it is the north.

The third type: judge the direction according to the wind direction. The sea sometimes blows wind according to the season, especially in the monsoon climate zone. In summer, since the ocean temperature is lower than the land, the ocean pressure is higher than the land, and the wind blows from the ocean to the land; in winter, the land pressure is higher than the ocean, and the wind blows from the land to the ocean.

Take China-China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-North China-Nor

If you are in the waters near China---North China and know the current season, you can roughly judge the wind direction and see the direction. Of course, this way of distinguishing direction is very difficult, and it is really difficult for ordinary people to master.

The fourth type: judge the direction of seawater flow. The direction of seawater currents is regular, generally flowing from high-pressure zones to low-pressure zones. If you can roughly determine your location, you can roughly judge the orientation based on the direction of the ocean current. This method requires proficiency in geographical knowledge and is more difficult and is not recommended as the first choice method.

The fifth type: use a compass. The compass is more convenient and accurate, but it must be prepared in advance and has good quality and accurate measurements to prevent errors caused by interference from magnetic fields and other interference. When measuring, avoid interference such as mobile phones and put them flat on your hands, try to avoid shaking. You can measure it several times more and take the average value.

These five methods can distinguish directions in the vast ocean so that you will not get lost in the ocean. However, if you have a boat or something, you can use the equipment on the boat to distinguish directions. There are many tools to distinguish directions on the boat, such as the very ancient compass and modern GPS systems. As long as you master the technology of using these things, you will not get lost in the ocean.

The compass is an operating tool of the Qi-Practice Practice. It is mainly composed of magnetic needles located in the center of the disk and a series of concentric circles. Each circle represents the ancient Chinese's understanding of information at a certain level in the universe system.

The ancient Chinese believed that human aura was controlled by the aura of the universe. Harmony between man and the universe was auspicious, and disharmony between man and the universe was evil. Therefore, based on their experience, they placed information at all levels of the universe, such as the stars in the sky, all things represented by the five elements on the earth, the heavenly stems and earthly branches, etc. on the compass.

Feng Shui masters use the rotation of the magnetic needle to find the most suitable direction or time for a specific person or thing.

Although the concept of "magnetic field" is not mentioned in Feng Shui, the coordination of direction, direction and spacing between the various circles on the compass implies the law of "magnetic field".

The invention and application of the compass is the result of human continuous exploration of the mysteries of the universe, society and life. The gradually increasing circles and increasingly complex pointer systems on the compass represent the practical experience accumulated by humans.

Of course, whether these experiences are comprehensive and correct remains to be further studied, but the information marked on the compass contains a lot of ancient Chinese wisdom.

In his book "The Application of Machines, Natural Forces and Science", Eun-Ges said: "The compass (compass) opened up the world market and established colonies."

This invention by the ancient Chinese was first used in navigation, which indeed promoted the emergence and development of capitalism. Magnetic needles were used for navigation, turning three-quarters of the earth into a general path.

In the 15th century, Columbus's crossing of the Atlantic Ocean to the American continent; in the early 16th century, the Magellan fleet's successful circumference was inseparable from the use of magnetic needles.

But international scholars have argued for hundreds of years when and how the magnetic needles were introduced to Europe.

In his Dialectics of Nature, Edges made a scientific conclusion on this, pointing out that “the magnetic needle was “transmitted to the hands of Europeans by the Arabs” from China,” it was around 1180.”

The predecessor of the compass is called "Sinan". The earliest record is found in "Han Feizi? Youdu Pian" in the third century BC. At that time, when people talked about the phenomenon of magnets attracting iron, they believed that it means "a kind mother's love - a son". Therefore, "magnetic" was once written as "Ci".

Sinan is like a household spoon, with a hemispherical bottom so that it can be easier to reduce friction when placed on a dial engraved with a "stem and branch" scale and easy to rotate.

In the Song Dynasty in the 12th century AD, Zhu Yu talked about the use of compass for navigation in "Pingzhou Ketan" and Xu Jing in "Goryeo Tujing". Some people say that the compass for navigation was too early, because according to the records of Liang Chenyue in the Southern Dynasty, the "compass boat" appeared in the Jin Dynasty.

According to Japan, the Secretary Volume 26, Qi Ming----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The guide chariot was used for navigation and attacking Su-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

By the Southern Song Dynasty, instrumental compass was made (a device that points out the direction of the magnetic meridian with a compass, called a compass), which was widely used in navigation.

The book introducing the compass in the West was first seen in the early 13th century, 100 years later than the records in books such as "Pingzhou Ketan".

In Shen Kuo's "Dream of the Moon River" by Shen Kuo in the Song Dynasty, the deflection angle of the water floating needle and the magnetic needle were recorded. Columbus discovered the deflection angle of the magnetic needle when he first crossed the Atlantic Ocean, which was more than 400 years later than Shen Kuo's records.

The liquid magnetic compass used on ships of various countries in modern times, which is an important creation in navigation technology. This design is based on the traditional European drought meridians, which absorbed the floating needle technology of my country over 800 years, making the magnetic compass increasingly perfect. This should be an important achievement in the exchange of science and technology between China and the West.

Before the invention of the compass, the ancients used the stars to distinguish the direction. They determined the direction by observing the North Star at night, and distinguish the direction by the shadow of the sun during the day.

A long time ago, our ancestors invented the compass and sundials to distinguish the direction of the earth. The sundials are the earliest compass.

Before the invention of the compass, the direction and orientation could not be divided very finely. The direction and orientation could only be described using eight major orientations: north, northeast, east, southeast, southwest, west, and northwest.

In Feng Shui, the Eight Trigrams are used to represent: the Kan hexagram represents the northeast, the Gen hexagram represents the northeast, the Zhen hexagram represents the east, the Xun hexagram represents the southeast, the Li hexagram represents the southwest, the Kun hexagram represents the west, and the Qian hexagram represents the northwest.

The sundial (gui) positioning divides the ground plane into twelve equal parts, and uses the twelve earthly branches: Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai to represent the direction.

With the development of the processing industry, the magnetic needle changed from the original spoon-shaped to the needle-shaped, and from the water floating magnetic needle to the use of a thimble, which caused the measurement accuracy of the compass to undergo a qualitative change.

In the Tang Dynasty, Yang Yunsong combined the two positioning systems of Bagua and Twelve Earthly Branches into one, and added all the ten heavenly stems of Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, and Gui to the ground direction system except for the Wu and Ji stems that represent the position of the central palace, to represent the direction.

Therefore, the 360 ​​degrees of the earth plane and the sky are divided into twenty-four equal parts. It is called twenty-four mountains, each mountain counts 15 degrees, and the three mountains are one hexagram. Each hexagram counts forty-five degrees.

The Twenty-Four Mountains have been preserved since the creation of the Tang Dynasty, so the Twenty-Four Mountains of the Territory are one of the main levels of Yang Pan.

The three mountains in the north are Ren, Zi, Gui, and the acquired Kan hexagram, and the innate belongs to Kun hexagram; the three mountains in the northeast are Chou, Gen, Yin, and the acquired Gen hexagram. The innate belongs to Zhen hexagram;

The three mountains in the east are Jia, Mao, Yi, and the acquired belong to Zhen hexagram, and the innate belong to Li hexagram; the three mountains in the southeast are Chen, Xun, and Si. The acquired belong to Xun hexagram, and the innate belong to Dui hexagram;

The three mountains in the south are Bing, Wu, Ding, and the acquired belong to Li hexagram, and the innate belong to Qian hexagram; the three mountains in the southwest are Wei, Kun, and Shen. The acquired belong to Kun hexagram. The innate belong to Xun hexagram; the three mountains in the west are Geng, You, and Xin, and the acquired belong to Dui hexagram, and the innate belong to Kan hexagram; the three mountains in the northwest are Xu, Qian, and Hai, and the acquired belong to Qian hexagram, and the innate belong to Gen hexagram.

As the founder of Yang Gong's Feng Shui technique in southern Gannan, Yang Gong not only created a complete Feng Shui theory, but also reasonably transformed the tool compass of Feng Shui technique.

The Twenty-Four Mountain Pans of the Territory were created by Yang Gong. Yang Gong did not have a complete Twenty-Four Mountain Pans before. There were only the Bagua Pans and the Twelve Earthly Branch Pans.

Although there were also marks of the compass of the Han Dynasty, the Bagua, the Earthly Branches and the Heavenly Stems, they did not divide the degrees evenly. Instead, the Heavenly Stems, the Bagua and the Twelve Earthly Branches were divided into three layers, and the degrees occupied were inconsistent.

Mr. Yang rearranged it and distributed the Bagua, Heavenly Stems and Earthly Branches in a plane direction, which was an epoch-making creation.

The horoscope plate of the twenty-four mountains of the territorial plate, namely the seventy-two dragon plate, was created by Yang Gong in his later years. Through long-term geomantic practice, Yang Gong found that Yin and Yang and the five elements are generally present in all directions, and the distribution of Yin and Yang and the five elements is determined to be inconsistent with the actual situation according to the attributes of the eight trigrams and the five elements. The Yin and Yang dragons are used to plot the dragons too roughly. Through repeated research, the heavenly stems are dominated by the twelve grounds, and the five elements of Na Yin are used to express the five elements of the dragon, which is called the "bian" five elements.

The "bending" mentioned in "Qingnang Aoyu" refers to the Na Yin five elements of the seventy-two dragons.

The compass consists of three parts: Tianchi: also called the seabed, or the compass.

The Tianchi of the compass is composed of a thimble, a magnetic needle, a bottom line, a cylindrical outer box, and a glass cover, and is fixed in the center of the inner disk. There is a pointed thimble in the center of the printing on the bottom of the round box, and there is a concave hole in the center of the bottom of the magnetic needle. The magnetic needle is placed on the thimble.

The direction at which the compass has an arrow is south and the other end points to the north.

A red line is painted on the bottom of Tianchi (under the sea) called the bottom line. There are two red dots on both sides of the northern end. When using it, the northern end of the magnetic needle should be used to coincide with the bottom line.

The seabed of modern compass is painted with cross-hairs, and the tops of the crosshairs are printed with southeast, west and north. When used, the north end of the magnetic needle should point to the north end of the seabed crosshairs, and the magnetic needle should coincide with the north and south lines of the seabed.

Inner disk: It is the rotatable disc immediately outside the compass.

There are many concentric circles printed on the inner disk, and one circle is called a layer. Each layer is divided into different equal parts. Some layers have more grids, some layers have fewer grids, and the least one is divided into eight grids. The layer with the most grids has three hundred and eighty-four grids, and each grid has different characters printed on it.

There are many types of compass, some have more layers and some have fewer layers. The most are fifty-two layers and the least is only five layers.

Various contents of the compass are engraved on different coils (layers) of the inner disk, which is the main component of the compass. Feng Shui techniques of each school include the main contents of the sect on the compass, making the Chinese compass a major encyclopedia of Chinese numerology.

External disk: The outer disk is a square shape, which is the tray of the inner disk. There is a small hole at each of the outer midpoints of the four sides. The red line is penetrated into the ten paths of the Tianxin, which are used to read the contents on the inner disk.

The ten paths of Tianxin are required to be perpendicular to each other. The new compass you just bought must be calibrated before using before using it.

The compass is a basic tool for measuring the magnetic azimuth angle of the earth's surface. It is widely used in various fields such as military, navigation, surveying, forestry, exploration, and construction.

The compass is actually a tool used to measure the direction of the horizon using the compass positioning principle. The compass is used in Feng Shui to garrison, eliminate sand, absorb water and determine the orientation of the building.

Shen Kuo (author of "Mengxi Bitan"), a famous scientist in the Northern Song Dynasty, discovered the existence of magnetic declination in the scientific practice of making and applying compass. He pointed out incisively that this is because the magnetic poles on the earth are not exactly at the north and south poles.

The compass and magnetic declination theory, that is, the ocean compass played a huge role in ocean navigation, allowing people to obtain the ability to navigate all-weather, and for the first time, humans gained the freedom to navigate in the vast ocean.

Since then, many new routes have been opened up, shortened the range, accelerated the development of shipping, and promoted cultural exchanges and trade exchanges between people of all countries.

The importance of the marine compass to the maritime industry cannot be overstated. Joseph Needham said: "Your ancestors were far more advanced than our ancestors in terms of navigation. China knew how to use the system of front and back sails to control the wind before Europe. Perhaps this is why there have never been many paddles and slave ships in the history of Chinese maritime navigation."

Of course, with the development of technology, it is rare to see such a compass. The most common tool for identifying directions on ships is the GPS positioning system.

However, there is no gps positioning system on Leng Xin now, even a compass or a compass, or even a watch (people nowadays rarely wear watches. With the mobile phone, the function of the watch has been gradually replaced!), so for Leng Xin, identifying the direction in the sea has become the second most important thing in his mind.

If you get lost in the vast ocean, Leng Xin believes that he would definitely be dead at that time. Fortunately, he temporarily escaped the disaster of life and death. He still has a great life to enjoy. Therefore, Leng Xin never wants to be buried in the ocean like this. He has to find a way out.
