How to win or lose mahjong?

Answer with the simplest words, paying attention to the bold and italic parts:

Chess rules: black first, then white, then black and white. One of your own pieces is not a "forbidden point" space intersection on the chessboard (you can't send it to eat, you can't play chess repeatedly). You can't move the pieces after playing chess.

Some vertically and horizontally connected (chess pieces) are not surrounded by the opponent's chess pieces or chessboard boundaries in all directions, so it is called "lifting" if the opponent can't face the situation before a round. In case of robbery, both sides should lift at the same time, and the players should lift each other's chess?

Game over: Both parties agree to end or give up the right to play chess (called "virtual").

Judging whether to win or lose: those with more enclosed areas win (sometimes it is required that black occupies more territory than white to win, which is called "sticky eyes", China rules stick 7.5 eyes, Japan and South Korea rules stick 6.5 eyes, and those who don't stick eyes are called "giving way") (or unprofessional: who has more balls on the chessboard).
