Probably know that you need to choose a date for your wedding and funeral. Mahjong won't choose a date, but winning or losing is very important. For anyone, a position is impossible once and for all, and it is not always suitable for winning. The time you said has just passed, don't miss this opportunity:

One of the "prosperous places" on the 7th of the solar calendar starts from 7: 00 pm to 7: 30 pm local time. Sitting facing west is invalid. It's best to play for only one and a half hours, because the tables are turned. If you miss it, wait for another time. People who play together must have no small moves, and they rely entirely on luck. Of course, you have a good chance of winning.
