I think it is an unpredictable thing for parents, but kindergarten teachers think it is parent-child interaction and for the growth of children. Nowadays, people are under great pressure, and some units simply don't have time to ask employees to take time off, so parents feel that kindergartens are tossing parents, because the current educational concept is to let children play freely, and some programs can't be separated from parents' participation, so it is best to understand each other.
