Yitong Autism Center is very good, and the teachers are very professional. In the final analysis, it is very systematic and formal. Parents are not allowed to watch the institutional training we went to before. You can watch it here. We also have parent training, which is especially professional. Children can't recover in such a precious few years, and they can't take detours and waste time. I know that some children here have recovered well, some have gone to kindergarten and some have gone to school. That's great. We should also refuel.
