Saiya Foreign Language on the 4th floor of Tianjin Book Building/KLOC-0 is a training school specializing in minority language teaching. You can ask there. They have a good reputation there and the teachers are very responsible. Their Japanese teacher, Chen, is an expert in Japanese and has a high level of lectures. Federal education teaches speed recorders and car marketers. Teaching Japanese is not as professional as Isaiah. I am telling the truth!
