As for gambling stones, it is called "one knife is born, one knife is dead". That's because people who bet on stones are crazy now. Many people don't know how to control and measure. When playing with gambling stones, they are reckless, so they are likely to die with one knife.
Because jade will be surrounded by a layer of stone when it is dug out, gamblers must first cut a knife on the stone and then judge whether the quality of jade is high or low. If this knife goes on, the quality of jade is very low, and it is likely to be wiped out.
Nowadays, there are more and more people playing stone gambling, and there are more and more tricks of unscrupulous merchants. Many people lose money, so betting on stones is also a very dangerous activity. If this knife goes on, they may lose a lot of money. And all this money was earned by businessmen who were behind the scenes.
So I also want to advise you here that if you want to play gambling, you should try to go to those formal occasions. Don't believe the temptation of some unscrupulous merchants. You must be more considerate and delicate. You know, you can't afford it without profit. No businessman makes you rich by betting on stones. So don't indulge in this high-risk behavior.
