When I was a child living in a urban village, the landlord was a truck driver who owned a small truck, and during that era, it was quite profitable.
The landlord was a seasoned alcoholic, drinking half a bottle of white liquor alone every night. Every few days, when he got drunk and returned home, he would physically abuse his wife, usually just slapping her a few times and cursing at her; when it got serious, he would use his fists and even drag her by the hair on the ground. Somehow, the two of them managed to live together like this for over ten years.
