Sha Zhu's Rebirth in the Courtyard: Starting with Hitting Someone in the Head

When Sha Zhu is reborn back to 1951, the first thing he does is not to make money or buy a house, but to knock someone over with a stick.
Isn't Yi Zhonghai always pretending to be a good person? He was knocked down in the middle of the night and locked in a private room for slow interrogation.
Isn't Liu Haizhong a gossip? All the money in the family disappeared overnight, and now they can't even find a grave to cry to.
Wasn't Yan Bugui known for being stingy and calculating? He secretly took all the gold bars and silver dollars he had hidden away for half his life.
Wasn't the old deaf man the one giving advice behind the scenes? The gold bars are gone, and the fact that his son ran away to Taiwan has been brought up again.
He Yuzhu didn't kill anyone first; he was even more ruthless than a murderer.
If you ask him what his attitude is towards the people in the courtyard house.
Torture them thoroughly, leaving none alive.
