What do you mean by giving each other fish eyes at the dinner table?

In our custom, putting fish eyes at each other on the wine table shows respect for each other, which is called "looking up". Generally, fisheye is for VIPs at the dinner table. . . Different places may have different sayings. At home, it may be for the eyes, as the friend above said. . . . There are rules for eating fish at sea, which are unwritten rules. The fish can't be turned over, but it's called right. It goes without saying that fear of capsizing is a taboo. . . I hope what I said is helpful to you.
