First of all, I want to popularize the concept of lobular rosewood Venus. The so-called Venus of lobular rosewood refers to the growth process of lobular rosewood, because it absorbs various nutrients from the ground and various minerals precipitate in this process. They are Venus that we see with our naked eyes.
As for why the lobular rosewood of Venus will disappear when rubbed, there are several possibilities that are empty:
1, in the process of playing lobular rosewood, start the dish directly, because sometimes people will sweat, and sweating will bring some belt of venus down during the dish, which means that the Venus you see will be lost. Process; There are even those who wear cotton gloves, but in this process, rubbing rosewood hard will also cause Venus to fall;
2, it is possible to buy fake goods, and many businesses are not good at counterfeiting, which is difficult to distinguish.
Well, the above points are the views of empty dream sharing. I hope it helps you. Want to know more and more professional knowledge, you can consult Kongkong by private letter!
