What does it mean to pitch a tent in the countryside?
It means: in the countryside, some people hold banquets. Their daughter and son got married, and he didn't want to go to the restaurant, because going to the restaurant was more wasteful and more economical at home, so he said that he would set up a tent at home. Then this means that the son or daughter is married. Some people go out to travel, set up a tent with simple tools, and everyone gathers here to eat and chat.
