"Did you agree to go into the mountain with them??" Wang Guilan hurriedly asked.

"Well, Mom, don't worry, I'll be fine with Da Hei and Xiao Hei when the time comes!" Seeing his mother's worried look, Zhang Feng smiled and comforted.

Alas, knowing that her son had already made a decision and would definitely not change it, Wang Guilan shook her head and only hoped that there would be no accidents at that time.

"Mom, don't you know my skills? Even if I encounter a tiger and a black bear, I'm not afraid, and besides, when I go into the mountains together, more than a dozen of us will go into the mountain together, and it is estimated that there will be police together, so you don't have to worry at all." Knowing that his mother was worried about himself, Zhang Feng also felt warm in his heart.

"Okay, just pay attention to yourself, and when the time comes, bring the big black and the little black with you, by the way! And bring the sparrowhawk too!" Wang Guilan was afraid that something would happen to her son, so she couldn't wait to let him take away all the combat power in the family, if it weren't for the big white, they were all cute, and they were probably all sent to the battlefield.

Zhang Feng hurriedly agreed, so that his mother could rest assured.

"Brother, we're back, look at the pebbles we picked up today, look at this piece of beauty, right?"

The little girl and Yiyi Zhang Lin came back from painting on the river beach, ran in with a basket of pebbles and a smile, and said to Zhang Feng as if offering treasures.

"Good-looking, good-looking!" Seeing the little girl's excited appearance, although Zhang Feng said this, he was a little unimpressed in his heart, because this girl was like this every day, she was startled, and she was excited to pick up a few stones.

"Hey, this one is ............" Suddenly Zhang Feng found that there was a stone that was a little different, as if it was a little unusual.

"What's the matter, is there anything special about this stone??" At this moment, Yiyi and Xiaolin walked in with a smile,

"Well, this stone is a bit like Huanglongyu!" Zhang Feng took the stone and looked at it, observed it for a while, felt the delicacy of the stone, and replied with some speculation.

"Huanglongyu, is there such a jade?" Yiyi asked in surprise.

Not only Yiyi, but even Xiao Lin and Xiaoyue were confused, they seemed to have never heard of this kind of jade, Hetian jade, Nanyang jade, jade or something, they had heard of it, but Huanglongyu, I really hadn't heard of it.

"Of course, this is a new jade ...... that was officially unearthed and hyped up ten years ago," Zhang Feng then introduced the ins and outs of Huanglongyu.

Huanglongyu was originally known as yellow wax stone. It has the color of Tianhuang and the hardness of jadeite, with good hardness, high permeability, and bright and rich colors. Because it is produced in Longling, and yellow is the main color, it is finally named Huanglongyu.

Before 2004, Huanglongyu was called Yellow Wax Stone, which is a kind of stone. Using chemical physics analysis, there is no difference between Hetian jade, jadeite, and Huanglongyu, they are all stones, but they look more beautiful than other stones.

In Longling County, Yunnan Province, a tractor is bought for 100 yuan, but no one processes it because it is not worth the processing fee. In 2004, there was a small trader selling jadeite in Yunnan Province, took a piece of yellow wax stone, and had to ask the carver to process a bracelet.

Since then, yellow wax stone has been used to process carved pieces, and in 2007, Yunnan Province issued a provincial standard and gave a Huanglongyu name. The price of Huanglongyu has soared. On February 1, 2011, the national standard of "Jewelry and Jade Names" (GB/T 16552-2010) was officially implemented, and the international standard topaz was named Huanglongyu in the standard. Moreover, it does not have the meaning of origin. This standard is applicable to jewelry and jade identification, cultural relics, commerce, customs, insurance, pawnbroking, asset appraisal, scientific research and teaching, literature publishing and other fields. "Huanglongyu has a national standard, and it has become jade in a proper way.

Before the development of Huanglongyu as jade, it was only collected and bought and sold as an ornamental stone, and was called "Yellow Wax Stone of Yunnan Province".

At the beginning of 2004, the market of good mountain material only a few yuan per kilogram, but now has risen to thousands of yuan or even tens of thousands of yuan per kilogram, good seeds, turf materials, mountain water, grass and flower materials due to the scarcity of resources, is a material can only be found, the price is in a rapid and sustained growth.

Its price has risen so fast that it has created a miracle in the history of jade.

According to the official statement, the main reason is that the excellent quality and unique and rich color of Huanglongyu have been highly recognized by professionals, investors and the general public, and the mineral reserves of Huanglongyu are far lower than the reserves of China's precious Hetian jade and Burmese jadeite

The amount is less than 400,000 tons, and only about 5% can be used, and high-quality material stones are even rarer), so Huanglongyu has the rare characteristics of precious gem and jade.

But in Zhang Feng's view, all this is fart, Ma Ma Pi is fooling everyone into hyping together, and the value of Huang Longyu will be speculated, otherwise, what will happen to the place where jade is produced, and what about the capital that has been hoarded in large quantities?

To say that the reserves of Huanglongyu are only 400,000 tons, Zhang Feng can only describe it, people who live in the south know that there are many places in this kind of stone, even if there are not many jade grades, but it must be more than 400,000 tons, Zhang Feng feels that the real reserves are expanded by ten times, and a hundred times are far more than that.

According to the official version, Huanglongyu is very rare, except for the main production area of Yunnan Province, only the eastern and southern regions have sporadic distribution.

But as far as Zhang Feng knows, not only Guizhou Province, but also nearby provinces and cities are distributed, but everyone has not yet begun to explore and develop, and even in Xijiang and other areas, there are a large number of exquisite Huanglong jade production, its quality is high, no less than the origin of Yunnan Province.

"Brother, is this piece of Huanglongyu valuable?" Hearing Zhang Feng's introduction, the little girl asked with a look of fascination.

"How do I know?" Zhang Feng rolled his eyes and continued: "I don't understand this thing, unless I specialize in playing with this jade, who knows how much it's worth!"

"Ah, you don't know either!" the little girl looked disappointed.

Seeing her appearance, Zhang Feng shook his head speechlessly, thinking to himself that I am not a jack of all trades, how can I know everything.

"Of course, the identification of jade is a very professional thing!"

"Then the quality of this piece of Huanglong jade should be very good, right?" Seeing this piece of frozen jade, Yiyi asked curiously.

"Well, this piece should be regarded as the best quality of Huanglong jade, but it's a pity that it's a little smaller!" Zhang Feng carefully looked at the jade in his hand, this stone was like the size of a duck's egg because it was washed by the river.

However, its quality is very high, crystal clear, golden throughout, like the grease on the hen's body, it is cold and smooth to the touch, and it is indeed a rare good stone.
