(1) The Confucius Center I have been going to is an old brand. It should not be too bad in terms of word of mouth and service improvement.
(2) In terms of cost, it is normal for everyone to want to find a cheap and safe month center like me.
(3) cost performance, this will basically be compared. After all, it depends on whether it is suitable for you.
These are some of my personal experiences, and I hope I can help you.
