What does a half-brother mean?

Brothers of different fathers and mothers are metaphors of false or unreliable brotherhood.

丠丠 extension: mostly used for comments. For example, "As long as you play XXX, you are my half-brother", which is similar to "You are my buddy". It is used to express your love and feelings for something. Find the happiness of the same person. Source: A line from the film "Evil Does Not Suppress Right" directed by Jiang Wen. The original sentence tells the American doctor "Gendler" about the "Blue Peak" of China Revolution: "We are brothers, we are brothers of different parents!" Brother, brother, irony. Mirror word: plastic sister flower.
