What did the older generation say about not eating beef on their son's tenth birthday?

Yes, in the past, plowing cattle was a strategic material, and people were not allowed to kill cattle. Killing cattle without permission is drunk. Only when sick cows are reported to the government can they be slaughtered, so it is difficult for ordinary people to eat beef.

There is also a saying that because cows can plow the fields and dogs can look after the house, they are both human companions, and not eating beef and dog meat belongs to semi-fasting. Belongs to the virtue of accumulating yin.
