Hello, personally, I suggest you ask Zhongyu pharmacist. I didn't know the registration policy at that time, so I asked them. I feel that their service is really good, maybe the marketing is better, and then I want to learn from them. In fact, this is mainly because the quality of their courses is very good. Liu and other teachers speak very well, and their prices are relatively expensive, which is a headache. It cost me nearly five thousand yuan in the end.
