Because three dishes and one soup were the hospitality standards of county-level cadres in the past, and the purpose of cadres going to the countryside was to lead the local people to get rich and run a well-off life, so the cadres with three dishes and one soup went to the countryside to get rich and run a well-off life.
The movement of cadres to the countryside is a movement carried out by the state in order to better understand people's lives and better narrow the distance between people and officials.
