Have you ever taught in Shuguang School (then Shuguang Middle School) in Hohhot?

Not exactly. Teaching refers to the education and teaching management of township primary and secondary schools in backward areas. Hohhot Shuguang School is the largest private boarding school with the best conditions and environment in Hohhot, and does not belong to township primary and secondary schools in backward areas. So teaching in Hohhot Shuguang School (then Shuguang Middle School) is not teaching.
