My brother was slapped by our supervisor, so I went there overnight, broke his front teeth with a punch, and fractured his ribs with two kicks.

My brother was moved to tears.
Later, he got promoted, got married, and changed cars.
My business failed, and I borrowed 200k yuan from him.
His wife answered the phone: "First kowtow three times to that supervisor, and pay 400k yuan in medical expenses. You cover half."
I was stunned: "On what basis?"
"Back then, when you hit someone, we paid 400k yuan to settle it. His promotion was bought with your fists. Now you come to borrow money?"
The call was hung up.
Later, I found out that my brother had been paying off debts all these years.
His wife would scold me every time she saw me.
