Taigong fishing means that the willing takes the bait? Where did it come from?

Interpretation metaphor is willing to trap yourself.

The source is anonymous, "Wu Wang demands Pinghua".

During the period of Shang Zhouwang, Jiang Ziya was idle and often went fishing by the Weihe River. His fishing method is very special. He uses a straight hook and never puts bait. While fishing, he sang:

"When the squire fishes, he who wishes takes the bait."

Although he didn't catch a fish for several days, he came to the Weihe River to fish on time every day.

Jiang Taigong's behavior finally caught people's attention. One day, a woodcutter named Wu Ji sat beside Jiang Taigong curiously and chatted with him.

Jiang Taigong introduced himself and said:

"The old man's surname is Jiang, his name is Shang Ziya, and his road number is flying bear."

Wu Ji heard Jiang Taigong call himself "flying bear", which made him feel ridiculous. He said:

"Like your old man, sitting by the Weihe River all day fishing, with a straight hook, let alone fish, maybe even shrimp can't be caught. It is ridiculous that a person who can't even fish should call himself flying bear. "

Jiang Taigong listened to Wu Ji and just smiled faintly.

Later, Zhou Wenwang heard that an old man was fishing with a straight hook by the Weihe River. He guessed that this man must be a wizard. So he brought a gift to hire Jiang Ziya. After Jiang Ziya entered the DPRK, he became a squire, a strategist, and later became a prime minister, assisting King Wen and cutting Zhou and establishing the Zhou Dynasty.
