"Well water does not interfere with river water" originally refers to astronomical phenomenon: three constellations do not interfere with each other.

"We know that' well water does not interfere with river water' is a metaphor for each tube, not interfering with each other. Literally, this word is also easy to understand. Well water belonging to groundwater and river water belonging to surface water are not connected with each other and naturally do not invade each other.

However, this' well water' and' river water' originally did not refer to the water on the ground, but to the water in the sky! Under the deduction of Hua Shao, there seems to be another story that subverts the three views. It turns out that the well originally refers to the well house in the twenty-eight stars, which is located in the present Gemini, also called the cave well, near the Milky Way, and the river refers to the Milky Way. In the northeast and southeast of Tokyo, there are two other places called Beihe and Tokyo. Therefore, in ancient times, people said that "well water does not interfere with river water" refers to the astronomical phenomenon that the three constellations "Dongjing", "Beihe" and "Nanhe" do not interfere with each other and live in harmony.

Starting from Li Shimin, this week's program explains the story of Liu Bang, the ancestor of the Han Dynasty. "Now many film and television literary works like to portray Liu Bang, the Han Taizu who was born in the market, as a local ruffian. There are indeed records about Liu Bang's hooligans in the history books, and it is Liu Bang's father who gives this evaluation to Liu Bang."

However, what Liu Bang's father said at that time was very different from what he said now. "But when Liu Bang's father accused Liu Bang of using this word, he hated that he had no ambition, no job and no income. It turns out that Liu Bang was very independent when he was young, and he didn't like labor and had no industry to rely on. Liu Bang's father was so anxious and sad to see his son. When he was angry, he called Liu Bang a rogue and said that he was not as good as his second brother. " It turns out that the word "rogue" gradually began to have the meaning of hegemony and arrogance in the Yuan Dynasty.
