What funny and interesting advertisements or slogans have you seen on rural walls?

Probably on a long-distance bus, I saw a small village on the side of the road. On the walls of the outermost houses was written the phrase "If you want to be rich, have fewer children and plant more trees." When I saw it, I really couldn’t understand. What’s the conflict between having children and being able to plant trees? If there are more children, wouldn’t there be more people planting trees? And why can you get rich by planting trees?

As I grew up, I realized that this was actually a kind of "sarcasm" for rural people. Most rural people have many children at home and make a living by farming. But at that time, family planning and the conversion of farmland to forests were also advocated. Therefore, rural people have become the focus of emphasis. Such big slogans are written on the walls to prevent them from having children and cutting down trees to use open space for farming.

I can understand this because I heard it from a classmate later. He said that when he was a child, he grew up in his grandmother's house, because at that time, there were always inspections of rural birth defects, and they were very strict. He already had an older brother at home, so his parents sent him to his grandma's house, and his household registration was listed in his grandparents' household registration book. When he was able to return to his home, his parents were not particularly kind to him. Moreover, his grandparents used to support him when he went to school. His grandparents are old and can no longer farm. Moreover, there was a subsidy for returning farmland to forest, and his grandparents used the money to support him when he grew up.

His story made me think of the meaning of such a big slogan. It was to always remind rural people to abide by that rule, because there were really many "hidden" children like him at that time. Unlike in cities, where there are only children everywhere, even if it is now encouraged to have a second child, many people are unwilling to do so.
