Is it legal and reasonable for special post teachers to be seconded to county high schools?

It is legal for special post teachers to be seconded to county high schools, because there is no provision that special post teachers can't be seconded during the three-year service period, but they can be seconded, just affiliated with the original unit.

Special post teachers are a special policy implemented by the central government for rural compulsory education in the western region. By openly recruiting college graduates to teach in rural schools below the "two basics" counties in the western region, we will guide and encourage college graduates to engage in rural compulsory education, innovate the supplementary mechanism of rural school teachers, gradually solve the problems of insufficient total number of rural school teachers and unreasonable structure, improve the overall quality of rural teachers, and promote the balanced development of urban and rural education.
