Why did Duchang's population decrease a lot?

1, backward industrial development leads to less employment opportunities, and some people can only choose to go out to make a living.

2. The bride price and other gifts are too high, which increases the burden of marriage and makes some young people with poor family conditions choose to leave their hometown and seek a better life and development in other places.

3. The high price level, especially at important nodes such as the Spring Festival, will lead to higher cost of living, which makes some people choose to leave their hometown to find better life opportunities in other areas.
