What is the etiquette of Go?

I have been playing Weiqi for 20 years. Let me briefly summarize the etiquette of Weiqi.

1, both sides go to the black spot first;

2. According to etiquette, forerunners usually put chess in the upper right corner of the board (stars, small eyes, etc.). ), this is the performance of respecting the opponent;

3. Don't make small moves, don't talk, concentrate on thinking and keep quiet when playing chess;

4. After playing chess, you usually put away your own chess.
