What does it mean to enter the public door to tell fortune?

What do you mean, a word enters the palace gate, but nine cows can't be pulled out?

When a word enters the public gate, it can't go out-"public gate" is the yamen; "Che" dialect, a verb, means to drag and transport by means of transportation. The original intention is that as long as a piece of paper is sent to the yamen, you are tired of litigation, and no matter how hard you try, you can't get rid of it. Zen is used to describe that once you are diagnosed, you will become very tired, which is what is said in Volume 12 of Wu Deng Hui Yuan and Jackson Tan Ying in Jinshan: "When you kiss with your lips, you lose your meaning. It is a dead end, but it is not a way out." For example, Volume 17 of "Five Lights Meeting Yuan" and "Zen Master Huanglong Huinan": "Q:' Doing nothing without doing it is still a golden lock. "Where haven't you tried?" The teacher said,' One word enters the public gate, but nine ox carts can't get out. "
