Know people skillfully when eating: you can tell people from which part of the fish you eat first.

Ingenious cannibalism while eating: You can see what kind of family this person is from the part where he eats fish for the first time. I have seen similar problems when browsing the web before. Looking back now, it seems that he ate the meat on the back of this fish, or it is possible that this is a child of a poor family. If he came here to dig a fish's stomach, then this person's family conditions should be good. If he comes up, he will find a thick skin.
