There is no salary for the pre-job training of three supports and one support. "Three Supports and One Support" refers to the selection of some outstanding college students from the high school stage to the grass-roots support for agriculture, education, medicine and poverty alleviation. After all, these young students have just left school and have no social experience and work experience. In order to meet the job requirements, relevant departments generally organize training before taking up their posts, and these trainings are not subsidized.
