Jiang Zhongtuo said incredibly: "Can you convince the expert group to take the initiative to change the sample library?"

No wonder Jiang Zhong asked them to be surprised. The expert group of the conference was composed of personnel dispatched by the Ministry of Natural Resources and the National Academy of Sciences. It is supervised by the Standards Management Committee and is strictly independent of the institutions participating in the conference.

In order to ensure fairness and professionalism, the core members of the expert group were even restricted from contacting outsiders during the conference, so even if Zhou Yuanhe came forward, it would not be possible to interfere with the expert group.

Jiang Zhong asked seriously and said, "Xiao Song, don't talk nonsense, this is really too whimsical."

Song Tao waved his hand with a smile, and then he saw a whiteboard behind Sun Liancheng's seat, so Song Tao pointed to the whiteboard and said to Sun Liancheng: "Please make it a little."

Sun Liancheng subconsciously wanted to refuse, but after he looked around, he found that everyone present was focused on Song Tao, so he could only let go of the way and stand next to him first.

Song Tao picked up the marker pen in the whiteboard groove, wrote down the green, Xinjiang, Russia, South Korea, and Canadian on the whiteboard, and wrote down the ratio 20% after each.

Song Tao explained: "This is the composition of the test samples used by Qin Qiongwen and I, and it is also the composition of the current expert group's inspection sample library. The proportion of Hetian jade from different origins to the total sample is the same."

"But this proportional composition is very different from today's market share."

Song Tao found a picture from his mobile phone: "Last year, the domestic market share of Russian materials reached 51%, the Xinjiang materials were 25%, and the green materials were 21%, and the addition of added materials and Korean materials did not exceed 3%.

Song Tao paused when he said this, and he blinked and asked, "Website Manager Jiang, do you think the proportion of the five major production areas in the inspection sample library of the expert group is exactly the same. Is this reasonable?"

Jiang Zhongtuo immediately understood what Song Tao meant and said in surprise: "Of course it's unreasonable!"

"The most Russian-made Hetian jade sold on the market, and the most Russian-made jades that major appraisal institutions need to appraise are definitely the most Russian-made jades. Therefore, the accuracy of Russian-made materials should account for the highest weight of the total accuracy rate, rather than simply taking only 20% of the simple and crude ones."

When Jiang Zhongtuo said this, he couldn't help but stand up and pace: "In this way, we have a very legitimate reason to ask the expert group to modify the composition of the inspection sample library."

Jiang Zhongtuo stretched out his index finger and said excitedly: "Bao Xie's three-link identification method is a weakness in identifying Russian materials, so once the expert group suddenly increases the proportion of Chinese and Russian materials in the inspection samples, the accuracy rate of Bao Xie will drop sharply!"

The technicians present also left their seats at this time and came to the whiteboard to watch the data listed by Song Tao on the whiteboard. When everyone understood Song Tao's explanation, they nodded and said, "It's indeed feasible."

Even Sun Liancheng, who had a prejudice against Song Tao before, looked at Song Tao in surprise after listening to the statement, thinking to himself: "I'm quite flexible."

There were so many technicians at the quality inspection station who sat for an afternoon, but didn't even squeeze out half of the punctuation marks.

As a result, when Song Tao came forward, he gave a solution in a few words. Why not surprise them if this could?

It’s not that Song Tao is better than so many people present, but that these people are all trapped in inertial thinking, like a group of stubborn donkeys, they have to find a breakthrough in technical details, but they don’t know that starting from the results will be unstoppable.

Just as everyone was discussing it enthusiastically, Hu Houqun summoned Song Tao over.

Hu Houqun asked with some concern: "Xiao Song, although the accuracy of Baohui's identification on Russian materials is not high, we are the same."

Hu Houqun participated in the research of the triple appraisal method throughout the process. He is most familiar with it except Song Tao. The difficulty of appraisal of Russian materials is already high, and even Song Tao's own method has only 99.3% accuracy on Russian materials.

In this way, if the proportion of Russian materials in the inspection samples is increased, the accuracy rate of Baohui will indeed decrease, but Huachang is the same as that of the large ones.

If it is not done well, Baoxiong and Huachang might become a pair of desperate mandarin ducks, both hanging on the southeast branches. If outsiders see them, they might be laughed at them to death.

However, Song Tao said confidently: "Director Hu, I have taken this situation into consideration."

Then Song Tao took out a piece of straw paper from his schoolbag and said, "After my calculations, considering that the samples selected by the expert group will be more difficult to identify, if they modify the sample library according to my proposal, we expect our accuracy rate to only drop to 99.4%.

"But the Baohui Association will directly fall to 98.8%. "Song Tao smiled and said, "Killing one thousand enemies will hurt yourself by 800. My idea is to compare with who has a thicker blood bar."

Hu Houqun took Song Tao's straw paper and Jiang Zhongtuo for a few minutes, and finally nodded: "No problem, I can basically believe it."

Hu Houqun gave Song Tao a thumbs up and praised: "Xiao Song, I did a pretty job this time."

After confirming that, Jiang Zhongtuo discussed with Hu Houqun: "Since the next method has been determined, I will call Ma Boliang to see if he can communicate with the expert group?"

Hu Houqun urged: "Okay, please contact him quickly. The expert group will start verification tomorrow. If you don't do it, it will be too late."

Jiang Zhongtuo signaled everyone present to be quiet, then took out his cell phone and dialed it to Ma Boliang. Unexpectedly, the phone was connected in just a few seconds.

"Hey, Lao Ma." Jiang Zhongtuo said enthusiastically.

However, before Jiang Zhongtuan said hello, Ma Boliang recorded a good voice from the other side of the phone: "Hello, I am Ma Boliang. Below is my automatic reply. The private number will be temporarily suspended during the industry standard setting conference. If you have any questions, please go through the formal process."

"Hello, I am Ma Boliang, here is..." Ma Boliang's reserved reply rang again.

"This old horse can be disabled even with the phone number." Jiang Zhongtuo frowned and hung up the phone.

Song Tao thought for a while and said, "Website Manager Jiang, you must have Director Ma's WeChat or something. Try to contact us in other ways?"

"He doesn't use WeChat very much." Having said that, Jiang Zhongtuo still opened the chat page and tried to send a message to Ma Boliang.

However, he still received an automatic reply: Hello, the use of this account is suspended during the conference.

Jiang Zhongtuo really felt a little confused this time.

He couldn't help but complain: "Lao Ma is the director of the Standard Management Committee. As a result, except for meeting at the opening ceremony, he has never seen anyone before and has no contact information. Do you want to evaporate the world?"

Hu Houqun sighed and said, "I just want to hide from us."

Jiang Zhongtuan was really worried now, because only Ma Boliang has the authority to command and dispatch the expert group. How can he find the expert group if he can't contact him?
