After 85 Girls: You Can Know The Fur And The Male And Female By Hand.

Blindfolded by hand, you can identify more than 60 kinds of fur in 3 minutes. You can also tell about the quality and quality of fur. A master's degree graduated from Northeast Forestry University. Fur Liu Wei, an appraiser, has done such a great job.

Magic 1: knowing the male and female

On the 24 day, the reporter saw the 85 girl in the fur specimen room of Lin Da mobile college. The reporter randomly looked for some fur from the herbarium to ask her to identify. Liu Wei, who wore an eye patch, began to scratch the fur from beginning to end, and then accurately described the identity, gender, adult, season and even distribution of the fur. Journalists feel the same feeling of stone marten, pine marten, sable, mink four kinds of weasel fur, but in her hands are very different. "Mink is a aquatic animal. Its structure is very special. It feels cool and feels more moist. Sable It is highly active and feels the most soft. Liu Wei explained that species can be discriminate according to the density and length of hair, such as the pure black ridges on the backs of big civet cats, which are longer and harder than the surrounding ones, and have bumps in touch.

"This is the Yellow Weasel, the male", and even the fur can be touched by hand. Liu Wei said that the thickness of the skin plate is an important characteristic of distinguishing the female from the female. The thickness of the skin plate can also be used as a criterion for judging the geographical area of the animals. "Taking the two leopard cats, the leopard cat is slightly thicker and the south is thinner," Liu said.

Now, Liu Wei can easily identify 165 or more than 1700 pieces of fur in the specimen room by hand, and the accuracy rate is 100%.

Magic 2: a variety of knowledge

In the past 1 years, Liu Wei has had rich experience of "actual combat". She can judge the fur of some of the tested animals by hand characteristics. "Sable is a national class I protected animal. Smuggling is found to be very puny. Illegal elements have stained the sable after being bleached and washed away in customs." Liu Wei took out a disguised sable and contrasted it with the normal. "You see, if you look at the color, no one knows what it is, you can recognize it with your hands."

On one occasion, the sample sent by the Department concerned was a piece of incomplete fur. She looked at her appearance as a herbivore. Judging by fur color and touch, it might be a golden borage. "We can initially judge the scope of narrowing by first hand feeling and the macroscopic morphological characteristics of the skin. After that, we can further confirm with the help of microscope and other instruments, which not only saves cost, but also works efficiently."

After processing and selling fur products on the market, tanning is difficult to identify by molecular biology technology. Once a small piece of fur was sent for identification. Because the fur was very small and dyed, it was hard to identify. From the natural curl and length analysis of Mao, she probably was a beaver or a beaver, and was identified as beaver after two samples. The colleague jokingly said, "the fur is not needed for the inspection, let the small and micro feel it, and know the status of it all over."

Magic 3: knowing texture

"My hands are probably naturally tactile and well-developed, so I can detect the nuances of fur." Liu smiles and says that he is "sensitive". When she was a child, she learned to paint and buy paper. She never listened to the shop. She started to touch the paper. The pencils of different types did not need to read the labels on the pen.

When he was admitted to Northeast Forestry University, Liu Wei had a strong interest in "fur study". He collate a set of "pocket books", and thoroughly characterize all kinds of animal fur. Once she was free, she went into the herbarium and spent the whole day in bed, thinking about fur's tentacles.

In the third year, Liu Wei won the blindfold recognition fur championship in the fur recognition competition of the whole school, and became an idol of many school children. Later, he joined the CCTV "champion 360" column, and won the national top eight.
