There are Hanna Korean School and Han Tong School. Han has many. If you search for "Shanghai Korean Training" on Baidu, you will jump out a lot, but at first glance, many of them are for promotion, and there are many advertisements, which is very boring.

I watched the "Hanna Korean School" which won the first prize in Baidu Snapshot, and then listened to their class. It's very good there, so I study there. Now I have learned level 3. I passed the primary examination in April this year. I am very happy. Now I will make persistent efforts and hope to get the intermediate level next year.

I strongly recommend that you go to Hanna to learn Korean. The money was not wasted.
