Wu Zetian is the only femaleemperor in Chinese history. She had two capable officials. One was called Zhou Xing and the other was called Lai Junchen. One day, someone told Wu Zetian that Zhou Xing was plotting treason. Wu Zetian ordered Lai Junchen to investigate this case. Since Zhou Xing and Lai Junchen were good friends, Lai Junchen did not know how to interrogate him. He thought for a long term and finally came up with an idea.
One day, Lai Junchen invited Zhou Xing to come to his home. They were drinking wine and discussing cases. Lai Junchen asked Zhou Xing, "Some prisoners would not admit their crimes after interrogated over and over again. What can make them confess?" Zhou Xing said, "That's easy. You just need to get a jar and just charcoal fire to burn this jar. Then you will ask him to come to stay in the jar. What kind of crime would he not confess?" Then Lai Junchen ordered his servants to find a jar and burnt it with charcoal fire as Zhou Xing suggested. Then Lai Junchen stood up and told Zhou Xing, "Someone said that you are plotting treason. If you don't confess, I have to ask you to come into the jar." Zhou Xing was very panic-stricken. He immediately kowtowed and confessed his crime.
"请君入瓮"指用某人整治别人的办法来整治他自己。 "请君入瓮" is a metaphor which means to treat somebody with the way he has devised against others.
例句:
1、他突然请你吃饭,你可要小心他"请君入瓮"的诡计。 He suddenly invited you to dinner. You have to be on guard against his trick of "using your method against you".
2、我们已经掌握他犯罪的证据,现在只要"请君入瓮",把他逮个正着就行了。 We have already got evidence for his crime. Now we only need to make him suffer from his own scheme and catch him red-handed.
