Folk traditional game name

We have been here in Yanzhou for six weeks, which is similar to what you said. That is, draw six lines horizontally and six lines vertically. One to five lines that can be connected obliquely are called oblique. Anything that can be connected horizontally and vertically is called Zhou, and you must play chess first. If there is an oblique circle, hold down the opponent's important chess, and then remove the held chess when it is full. If the chess is diagonally connected, then remove the important chess of the opponent. In the end, whoever doesn't play chess loses.
