The Grand Canal of Beijing and Hangzhou was mobilized to attack Qi in the north and compete for the hegemony of the Central Plains. In order to advance northward to attack Qi and compete for the hegemony of the Central Plains, the Beijing-Hangzhou-Northeast canal, which was passed through Sheyang Lake to Huai'an and into the Huai River, and then opened up the historical mission of this river. After the Sui Dynasty unified the world, Emperor Yang Guang of Sui Yang of Sui used more than two million people to drive a canal from the Beijing-Huai section to the south of the Yangtze River to the south. Unfortunately, the dragon boat of this generation and the debauchery of the desolate emperor did not swim on the canal he built for too long, and he died on this dragon boat.

As soon as the Sui Dynasty was destroyed and the Tang Dynasty flourished, the canal was tossed and turned for hundreds of years, and finally fell into the hands of Kublai Khan, the ancestor of the Yuan Dynasty. The emperor, who owned the largest empire in the world, began to repair the canal that had been tossed and turned for thousands of years.

After Kublai Khan established his capital, he had to transport grain from Jiangsu and Zhejiang to Dadu. However, the Grand Canal of the Sui Dynasty, in the middle of the Haihe River and Huai River, stretched to the northeast and southeast with Luoyang as the center. In order to avoid detouring Luoyang and cutting bends and straightening, Kublai Khan asked people to build Jeju, Huitong, Tonghui and other rivers in order to concentrate the grain from the sea and river transportation to Tongzhou and transport it to Dadu.

Tonghui River is located in the eastern part of the capital. It started construction from the 29th year of the Yuan Dynasty to the Yuan Dynasty. It was under the leadership of the construction of the Yuhe section. It is said that not only migrant workers dig the river, but officials of the court also participated in the construction. The project was completed in the autumn of the next year. At that time, the grain ships in the south of the Yangtze River were crowded on the northeast bank of Jishui Pond, and the boats were also sailing on the Yuhe River. People in the capital were rushing to watch and cheer warmly, just like celebrating the festival. Kublai Khan, the ancestor of the Yuan Dynasty, was returning from Shangjing Helin. On Wanning Bridge, he saw that the water was covered with grain ships. "When passing Jishui Pond, I saw the water blocking water.

, , , "Great Joy", personally named the river from Wanning Bridge to Tongzhou as "Tonghui River", and the river name of "Tonghui River" was born from Kublai Khan. Nowadays, people generally call the section of the Northern Canal of the Grand Canal Lu River, and the section from Dongbianmen to Tongzhou as Tonghui River. However, before the Yuan Dynasty, the Tonghui River is now called Lu River, and the Jinzha River is called Jinzha River. Because it also passed through the Lu River during the Jin Dynasty, there were gate dams built. The section from Wanning Bridge to Jinzha River is in the capital and flows through the imperial city roots of the Yuan Dynasty, it is called "Yu River", also known as "Yu River". This Yu River is the end of the canal!

At this time, a dusk shone slanted in Tonghui River. Not far away, a small boat slowly anchored under a willow tree on the dock of Tonghui River. Soon, a man and a woman walked down from the boat. Look at the two of them, the man was dressed in a long gown, a coarse cloth skirt, and the woman was dressed in the same farm clothes, but her skin color was obviously much whiter and smoother than that of ordinary farm wives. It can be seen that she had lived a wealthy family for the past.

The man carefully supported the woman to the shore and looked at the banks of Tonghui River. But he saw that the small pier was very prosperous, with taverns, inns, restaurants, teahouses and various seafood on the sea on both sides of the pier.

"I can't tell that the banks of this small Tonghui River are quite prosperous?" The man sighed sincerely at the bustling streets on both sides of the river.

"Of course, you came to the wrong time. If you come next June, it will be even more lively and prosperous!" the woman turned around and said with a smile.

"Is that true!" The man tied the bow of the boat and turned his head and said, "Is there any speciality in June?"

The woman said, "Brother Xiao, do you know that the Tonghui River is the most prosperous. When Emperor Shizu Emperor Kublai Khan ordered the unblocking of Tonghui River, a section of the Yu River was completely dug. Later, because the Yu River either became a dim river or disappeared, people forgot the Yu River. The Tonghui River was unblocked, because the food and various goods in the south were continuously transported to the capital, and the northeast bank of the Jishui Lake became the final dock of the Grand Canal, so the Jishui Lake was very prosperous, especially the Jishui Lake on the northeast bank. Every June, lotus flowers are the most prosperous and ladies gather. Whenever the flowers bloom, the scenery is the best. Green willows droop, red clothes and powder are greasy, and the flowers are all over the face. I really don't know how people are, and flowers are flowers." On the Yu River, there are cargo ships coming and going, and the scenery is magnificent. The two sides are also adjacent to shops, just like Qinhuai, Jiangnan.

"I didn't expect that this northern part of the border would have beautiful scenery in the south of the Yangtze River. It's really rare?" The man looked at the pier and said to himself.

As the two were talking, there was a sound of horse hooves far and near. The two looked at each other, but they saw a small group of soldiers wearing court clothes coming. Soon the team of troops came over. The leader was very tall, wearing armor, and a round face with a hint of fatigue. They stared at the dock with their eyes straight, and they didn't see a man and a woman standing on one side of the horse's head.

"Brother Xiao, isn't that Deputy General Han? Aren't they fighting in Gaoyou? How could they come here?" The woman looked at the man on the horse and muttered at the man beside her with curiosity.

The man did not answer, but followed the team of people. There were not many people coming, dozens of them, all of whom were covered in dust and looked extremely nervous. They followed the man in the lead and ran towards the dock.

"Boatman... we are about to cross the river. What's the matter with you, old man? I asked you to prepare four boats yesterday. Why are there only two boats now? You still told me not to wait for crossing the river?" The man in charge rushed to the dock, turned over and dismounted, and waved his hand and pulled over a thin old man sitting at the dock, and shouted loudly.

The old man seemed a little afraid. He was held in his hand by the man in the leader. His thin body kept trembling and said with a trembling face: "Several Junyi, the boat you want this time is too anxious. Yesterday, many officers and soldiers like Junyi came up on the dock. They took it when they saw the boat. The two boats borrowed by the young man yesterday were all suppressed. These two boats are all the property of the young man. The four boats are really... I beg Junyi to be kind to you. For a few more days, the young man will definitely find a good boat for Junyi."
