Getting Rich in the 1960S

Qin Hao was bitten to death in a zombie siege and traveled through time to become Qin Hao, a "second-rate son" in the 1960s. We live in an adobe house and eat sweet potatoes and taro. We need a certificate to go out, and we need to see a ticket to buy meat. After traveling to this era, although he didn't have enough to eat or wear warm clothes, he was at least safe and Qin Hao was very satisfied. It's just that the boy from the village chief's family keeps giving him blank stares, and he doesn't know why?
