I will immigrate to Japan next March and want to learn Japanese from now on. I hope you can give me some advice.

I also came back from studying abroad, and I also went through your stage ~ Hehe, I was as basic as you when I went abroad. At that time, I enrolled in a four-month full-time Japanese elementary class, starting with standard Japanese and Japanese for everyone. I am not from Dalian, so I can't introduce you. In choosing a school, I suggest you choose grammar, a full-time course taught by Professor China, or you can listen to it before making a decision. Because after going abroad, everyone in the school speaks Japanese except China people. It will be hard to go out and start life without learning a solid point!
