Jano's system is so chaotic that it has been useless for a year. I see. Meng Tong's is ok, more inclined to early education; We chose Tuoyoubao, and I personally like Tuoyoubao very much. Not only is it easy to use, but also the key design is beautiful, which greatly improves our efficiency. Unlike the school treasures and school housekeepers we used before, deep blue is very depressed and completely ignores the feelings of users!
