The phrase "blood is thicker than water", literally translated from "The blood is thicker than water", is a famous saying uttered by a US military general during the Second Opium War.

The phrase "blood is thicker than water" records a period of history in which Western (white blood) powers joined forces to massacre the Chinese (yellow) regardless of diplomatic norms. It was two gangsters working together to bully a weak person." The theoretical basis of "hit you without negotiation" is the best embodiment of the "law of the jungle" that has been used in international politics to this day, and this word is still a reasonable code of conduct in English.

However, the word "blood is thicker than water" is widely used by the Chinese and extends to family affection, which is very different from the original meaning of the word.
