Visiting a child care center in Vietnam

This morning my husband and I went to visit a child care center which was located in the countryside. I introduced myself to the principal who at the beginning didn't want me to look at the center, but after I showed her my City College ID, then it was o.k. She took me to see a classroom where the children were singing already with their teachers. The center has 250 children. I observed that the health conditions were excellent; the classrooms were neat, orderly and the floors were super clean. All the children must take their shoes off before going inside the classroom and greet the teacher. Each child has his own cup to drink milk or juice. The children seem to be well-adjusted and they seem to be secure about themselves.
