Siheyuan, My System Is Weird

[No harem + no female protagonist + violent temper + male protagonist concentrates on his career and does not lick everyone in the courtyard] One day in 2023, Qin Weiguo was working on the assembly line. Due to a system loophole, he traveled to the courtyard and transformed into Qin Weiguo, who has the same name and surname as him. How should he deal with the beasts in this courtyard? On the first day after entering the hospital, he was falsely accused and made medical trouble. On the second day after entering the hospital, the widow knocked on the door.
