I once went out to a hotel for dinner with my colleagues. Why can't I eat fish instead of fish?

Instead of facing the fish, let the fish turn over and eat.

This is the earliest coastal custom. Ancient fishermen were most afraid of capsizing when they went out to sea to fish, so when it comes to eating fish, they are afraid to say "turn the word". Over time, it has become a custom, and now it extends to turning fish when car drivers are very taboo to eat fish.
