"How did you determine where to go with the knife? So accurate. Zhuang Rui asked, he had just noticed Huang Chong's action of observing the discarded piece of rough stone wool, and he was a little ashamed in his heart, no wonder Huang Chong was able to pick a good jade in a pile of discarded bricks, this kind of learning ability and attitude was what he lacked.

In order to learn, Zhuang Rui also carefully observed and found that Huang Chong's judgment was very accurate, especially the first knife.

"There's an element of luck in that." Huang Chong said, this sentence is not false at all, there is indeed an element of luck, otherwise it would not be so accurate, and Huang Chong does not have a pair of see-through eyes.

"What about the other part?" Zhuang Rui took out the stone and put it in front of Huang Chong, and asked, this is the abandoned rough stone that was cut by the first knife, and he "collected" this piece.

"You kid, you really haven't changed." Seeing this piece of wool, Huang Chong said with emotion, he immediately understood what Zhuang Rui meant.

"Hey, brother, how did you pick up this piece of?" Gu Dingyu was surprised, Zhuang Rui's actions just now were very secretive, and everyone didn't notice it.

"Take it as a warning." Zhuang Rui said.

"As a warning?" Gu Dingyu was stunned when he heard this.

"Yes, this time because the pile is bricks, I was careless, I didn't take a good look at it carefully, and I took this stone and used it to warn myself in the future, at any time, I must not be negligent." Zhuang Rui said with a smile.

Gu Dingyu looked at Zhuang Rui for a while, and saw that his hair was straight, and then Gu Dingyu gave a thumbs up and said, "Brother, you are amazing, admire!" ”

"Tell me how you judge." Zhuang Rui ignored Gu Dingyu and looked at Huang Chong.

"Actually, it's just a little speculation." Huang Chong took half of the rough stone, and according to the texture on it, he said his judgment: "If I do it again, I will choose to rub the stone first, and then cut it." ”

Generally speaking, there are two methods of cutting jadeite rough - rubbing stone and cutting stone.

Cutting stone is the most critical step in the process of gambling stones, the so-called "a knife to live, a knife to death" is to cut the stone, the jargon says "rubbing up is not rising, cutting up is considered to rise", it can be seen that the conclusion of winning or losing is to be determined by the knife of the stone.

Compared with the cut stone, it belongs to a more conservative method of calcifying stone, experts call rubbing stone "rubbing skin", "molting", a piece of jadeite rough stone to rub the stone, generally have to find the appropriate stone rubbing position on the rough stone.

Rubbing the stone in the appropriate position, the calcite effect is good, and the risk is small, but if you don't find the right position to blindly rub the stone, it is possible to accidentally untie the green away, when you find the appropriate position to rub the stone, you can observe the inside of the rough stone with the help of an external light source from the wiping position, so that you can further judge the situation inside the stone more accurately.

There is only one purpose of rubbing stones, and that is to find the real green, and then find the direction of the knife.

It's not just Zhuang Rui who is learning, Huang Chong is also reflecting, and there is always nothing wrong with being cautious in dealing with anything.

The three young people exchanged ideas based on the knowledge of gambling stones, at first Huang Chong told his judgment, and then Gu Dingyu took over the conversation, his theory and experience are very rich, there are things to say, and he talked a lot about his own understanding, Zhuang Rui and Huang Chong also put forward some opinions from time to time.

Although Huang Chong and Zhuang Rui did not have much experience in actual calcification, their memory and understanding were amazing, and after a week of assault, they also memorized a lot of theoretical knowledge, and Gu Dingyu's words inspired the two of them.

In the end, Gu Tianfeng and Zhou Lao also joined the chat and told the three of them a lot of their personal experiences.

Zhou Lao, whose name is Zhou Ruisong, is the president of the Beijing Jade Association, the secretary general of the National Jade Exchange Association, and a professor of Shuimu archaeology.

……

"Let's go, Zhuang Rui, let's practice it again, review and review." Huang Chong said with great interest.

The so-called "true transmission of a sentence, false transmission of ten thousand books"!

After listening to Gu Tianfeng and Zhou Ruisong's guidance, Huang Chong had a feeling of sudden penetration, combining his experience, knowledge from books and their guidance, which made Huang Chong have the urge to do it again.

"This ......" Zhuang Rui hesitated a little and looked at Gu Tianfeng, after all, before he came, Gu Tianfeng asked him to only see but not buy, and he had actually broken the contract just now.

"Then you go and have fun, theory and practice, but Zhuang Rui, I have a request, grandson, Xiao Chong, neither of you can lend money to Xiao Rui, what stones you can find, it depends on your own ability." Gu Tianfeng said.

"Okay." Zhuang Rui nodded, he had no intention of borrowing money.

"It's two good seedlings." After the three left, Zhou Ruisong said: "In the jade industry, I haven't seen such a spiritual newcomer for a long time. ”

"Hmm." Gu Tianfeng also nodded with satisfaction.

"Zhuang Rui is your godgrandson, so Huang Chong should have nothing to do with you." Zhou Ruisong said.

"Lao Zhou, you, don't think about it, Huang Chong, this kid, gambling is just an interest, it is unlikely that he will be deeply cultivated in this industry, he is a famous entrepreneurial genius of Beijing University, a genius in computers, known as 'Bill Gates of Beijing University', if you want to accept him into the door, it is almost impossible." Gu Tianfeng saw through Zhou Ruisong's thoughts at a glance and said.

"So powerful?" Zhou Ruisong was taken aback.

Although he doesn't know much about business, he still knows the name of Bill Gates, the richest man in the world.

"Uh-huh, do you know about shared bikes?"

"Of course you know, you really think I'm an antique!" Zhou Ruisong said.

"Bicycle sharing, he started tinkering the year before last, and he was the first person in China and even the world to enter this field, but he made a profit from the company before, and he has been resting recently." These news were all known by Gu Tianfeng from Zhuang Rui.

"Sure enough, God favors a few people, and is so powerful in every field." Zhou Ruisong shook his head and sighed.

"It's a pity!"

There are many cattle in this world, not only in one industry, but also in other industries.

This is like when high school Chinese science is divided, ordinary people are good at what to read, and those who are very bullish are very good at both liberal arts and science.

……

Huang Chong and the three of them came back to the gambling stone area, and the three of them separated.

Although he didn't say that he wanted to compete, Gu Dingyu and Zhuang Rui both had the idea of competing in their hearts, after all, Huang Chong just now opened a good jade from a brick material that they were not optimistic about, which was also a slap in the face to some extent.

On the one hand, the price of half gambling is too high, after all, the half gambling material that can be placed here belongs to the rubbing flowers, and the gambling is much stronger than the full gambling material, and they can't show their ability.

However, the three of them are still different, Zhuang Rui mainly chooses the cheap area, because he can use not much money, Huang Chong is more casual, he has money, even if it is the most expensive rough stone here, Huang Chong can take it without blinking an eye, he doesn't care about the price of the rough stone, he just wants to combine the theory and find a stone that satisfies him.

"Huh?"

Huang Chong, who was looking at the rough stone, was suddenly hit in the back, and the person hit the table, knocking the rough stone on it to the staggering, almost wanting to fall......
