The Sihui mentioned by Gu Changming refers to the Sihui Jade Shopping Mall in Huachang City. More than 80% of jade retailers in the city will purchase goods there, and some customers who buy zeroes will come to buy, which is very well-known.

To be precise, the four associations in Huachang City should be called "Xiao Sihui". The real "Sihui" is a place in Yuezhou Province, which is the largest jade wholesale distribution center in the country. The Sihui Jade City in Huachang City actually took advantage of its popularity, but it was quite successful.

However, the huge number of merchants and customer flow in Sihui Jade City will inevitably lead to a mixture of things. Customers can buy jade with extremely cost-effectiveness there, or they may spend a lot of money to sell inferior products that have been replenished, dyed, and bleached.

The place where Gu Changming is going to secretly visit is still challenging.

If Gu Changming could choose, he would rather cooperate with the masters in the jade market in terms of jade.

Because he once heard that professional appraisers mainly rely on equipment for testing jade. If they leave these equipment, their eyesight is actually not as good as those masters who have been in the jade market for many years.

Song Tao usually comes into contact with crystal gems like red and sapphires, but he has also studied the naked eye judgment method of jade, and he is confident that he can distinguish the authenticity of jade.

So Song Tao agreed: "No problem, when will we meet next time?"

Gu Changming kept observing Song Tao carefully. When he saw that Song Tao was confident and still remained the same, he felt a little more at ease.

Gu Changming said: "Today's case of gold and jade is very valuable. We need to spend some time organizing the collected audio materials, so I plan to go to the secret visit of Xiao Sihui three days later. We will discuss the specific time depending on the situation."

"Okay, I can rest for a few more days." Song Tao agreed. The amount of this undercover investigation was much greater than he thought. He had no idea how many circles he had circled in the huge Huamao Mall this afternoon.

Compared to identifying gems in the group, undercover investigation is definitely a chore.

Thinking of this, Song Tao couldn't help but ask: "Team Leader Gu, are you rewarded for doing these jobs?"

Gu Changming smiled bitterly and said, "We are the long-term consumer rights protection volunteers of the Consumer Association. Volunteers, strictly speaking, they are voluntary labor and no wages."

Song Tao has never been a volunteer. When he heard Gu Changming say that he had no salary, he couldn't help but ask in surprise: "No salary? Then how do you make a living?"

Gu Changming smiled: "Although we don't have a salary, we have subsidies from relevant departments. In addition, last year's March 15th Gala was listed as a key support work, and the subsidies have increased by a large amount. Ordinary volunteers have 4,000 yuan per month, and team leaders like me will be higher."

"Of course, we volunteers mainly rely on faith, and rewards are secondary." Speaking of this, a hint of pride appeared on Gu Changming's face.

Song Tao was stunned for a moment. He could feel that what Gu Changming said was heartfelt. He was just a big city like Huachang City with 4,000 yuan a month. Gu Changming looked at least over 35 years old. Even if he could get more subsidies as the team leader, it would be far from enough.

After Song Tao officially took office as the intern team leader, he did not count as a bonus, but his basic salary alone was enough 10,000 yuan. In contrast, Gu Changming and his volunteers could be considered as a contribution without asking for anything in return.

Although Gu Changming had been doubting his ability, Song Tao thought that Gu Changming was eager to do a better job in charity, so the knot in his heart was untied.

So Song Tao smiled and joked: "I said why Team Leader Gu dislikes us ordinary appraisers so much. It turns out that he has a great mind."

"No, no." Gu Changming waved his hands repeatedly and said embarrassedly: "Actually, the reason why I want Huachangdi to assign more powerful technicians is also selfish."

Song Tao was intrigued: "Can you explain it in detail?"

Gu Changming said frankly: "Everyone hopes that their work can be recognized, and volunteers like me are no exception."

"My group has been rated as excellent for four consecutive years. Last year, we found evidence of Zhongda Automobile's frequent failure due to water inlet in the engine. In the end, this case was only one vote short of the 3.15 party."

"At that time, we were determined to attend the 3.15 party next year to show our work results. Unexpectedly, we won the 'death group' like this in the jewelry industry this year. If there were not enough powerful technical personnel to help me, I was afraid that I would not even be able to evaluate the excellence."

Song Tao is an insider who doesn’t understand the suffering of a layman, so he said disapprovingly: “What’s wrong with the jewelry industry?”

When talking about the topic of the jewelry industry, Gu Changming suddenly became excited: "The water in your jewelry industry is even deeper than that of the Mariana Trench!"

He complained to Song Tao with a frown, "I wanted to sharpen my gun before, but I read the book called Gem... Systematics? There are so many gems in it, and I see that they all look exactly the same except for the color."

Song Tao corrected: "It's Systematic Gemology."

Gu Changming slapped his forehead: "Yes, you professionals still understand. I even remembered the title of the book wrongly, let alone those professional things."

Song Tao smiled. Through this conversation, his impression of Gu Changming changed greatly. Although Gu Changming was a little selfish, Song Tao didn't mind helping him. After all, it was considered to do his part for public welfare.

......

The next morning, Song Tao finished his rest time and came to Jiang Zhongtuo's office.

He thought about the feasibility of identifying the origin of Hetian jade overnight last night, and finally decided to use this as his SCI area 2 paper topic.

Song Tao rarely stayed in the school department during this period, so it is more convenient to ask the teachers of the quality inspection center for academic issues, and Jiang Zhongtuo is obviously the most suitable person.

After Song Tao came in, Jiang Zhong asked with a smile: "Xiao Song, how did you contact the Consumer Association yesterday?"

When talking about this, Song Tao couldn't help but shrugging and said helplessly: "Of course there is nothing wrong with me, but they disliked my level and ability not being enough."

"I think you are not capable enough? Then they really should go to the ophthalmology department for treatment." Jiang Zhongtuo chuckled: "Why, is the Consumer Association asking for a replacement?"

Song Tao shook his head: "There is no need for this. I sent them away in a few words. And I have made an appointment to go to Xiaosihui in two days to check the situation."

Jiang Zhongtuo said with satisfaction: "I know it's definitely right to send you there. You guys have some skills besides doing research, and you are also very good at speaking. You can solve any difficult things you encounter."

"Is there anything wrong with me today?" Jiang Zhongtuo asked about serious things after chatting for a few words.

Song Tao said: "Webmaster Jiang, you told me before that undergraduates apply for intermediate professional and technical qualifications in exceptional cases. I have published a SCI Zone 1 article, and I am still missing two SCI Zone 2 papers."

"Yesterday I went to Huamao Mall and saw a merchant selling Hetian jade, so I thought I could study the method of identifying the origin of Hetian jade, and this topic is more practical. What do you think?"

"Identify the origin of Hetian jade?" Jiang Zhongtuo frowned when he heard this and put down the teacup in his hand.

Song Tao felt that Jiang Zhongtuo did not quite agree with his idea and asked in confusion: "Webmaster Jiang, the domestic industry standards are currently blank in the identification of Hetian jade origin, which must be because the existing technology is not perfect enough."

"Although my research may not necessarily affect the national standards of the jewelry industry, it can at least show that this topic is valuable," Song Tao added.

Jiang Zhongtuo did not answer Song Tao's question immediately. He was silent for a few seconds, then got up and stood by the window.

"Song Tao, although your professional knowledge and scientific research awareness are the top undergraduates, you are not at the forefront of academics, and you do not understand some aspects." Jiang Zhong said.

"Webmaster Jiang, is there any other reason why industry standards do not allow appraisal agencies to mark the origin?" Song Tao was stunned for a moment and asked quickly: "Can you tell me what the situation is?"

Jiang Zhongtuo explained: "The academic community's research on the origin of Hetian jade is more in-depth than you think. According to the most scientific method at present, the accuracy rate can be conservatively estimated to reach more than 95%.

Song Tao said in surprise: "That high?"

It is impossible to be 100% correct in identification. If calculated based on the accuracy rate of more than 95%, it can be considered that the academic community today has the ability to identify the origin of Hetian jade.

Song Tao immediately asked in confusion: "Since the accuracy rate has reached such a high level, why don't major institutions allow major institutions to identify the origin?"

"Is it because the standards currently implemented were revised a few years ago that they can't keep up with the pace of scientific development?"

The current standards implemented in the jewelry industry were revised three years ago. In this era of rapid development of scientific research and technology, there is a high possibility of earth-shaking changes in three years, so it is reasonable that the old standards lag behind the times.

However, it is said that the latest jewelry industry standards will be released in a few months, so Song Tao asked: "Webmaster Jiang, will the new standards allow us to identify the origin of Hetian jade?"

Jiang Zhongtuo shook his head and said, "No, I'm sure that the latest industry standards will not add regulations on the origin of Hetian jade in a few months, because in essence this is not a technical problem."

"Isn't it a technical problem?" Song Tao asked: "Webmaster Jiang, what's the problem?"

At this point, Song Tao finally realized that Jiang Zhongtuo had been trying to speak out on this issue, as if there was something ulterior motive.

In Song Tao's impression, Jiang Zhongtuo has always been a straightforward and open-minded person. He has never seen Jiang Zhongtuo hesitate like today.

Song Tao thought to himself: "There must be a deeper reason."

Jiang Zhongtuo hesitated for a while, and finally said slowly: "You are now the team leader of the quality inspection center, and you can barely be considered the leadership. It's okay to tell you."
