In 266 BC, Zhao Huiwen, the monarch of the State of Zhao, died, and his son Taizi Dan was succeeded by Zhao Chengxiao. Being young, his mother Zhao is in charge of handling state affairs. Zhao is a wise and knowledgeable middle-aged woman. When she was just in charge of state affairs, Qin stepped up her attack on Zhao.
Idiom story
Zhao was in danger and asked Qi for help. Qi asked Zhao to send her youngest son to Qi as a hostage before sending troops. Zhao was reluctant to leave his youngest son, but after listening to the minister's advice, he often sent to Qi. Qi sent troops to help Zhao beat back Qin Jun.
On one occasion, the King of Qi sent messengers to Zhao with letters to greet him. Wei Hou asked the messenger before opening the letter. "Qi's harvest is not bad, is it? Are people safe? Is the King of Qi healthy? " The envoy of the State of Qi was very unhappy and said, "I was sent by the King of Qi to greet you. Now, don't ask the king of Qi, ask the harvest and the people first. Can you put the humble in front and the noble in the back? "
Wei Hou smiled and said, "No.. If there is no harvest, how can anyone? If there is no people, how can there be a monarch? Can you give up the basics and just ask the questions on the side when you say hello? " Hearing this, the emissary of Qi was speechless for a moment. This allusion to "innocence" later evolved into the idiom "innocence".
