If you want to learn Japanese, you must first think clearly whether you really want to learn Japanese.
Full-time Japanese is a comprehensive choice. The so-called full-time Japanese is to leave work and enter the school for all-weather Japanese study. Although this model will take us a long time, we can master Japanese more firmly by constructing the framework of Japanese knowledge system. After studying for a period of time, we won't feel embarrassed or forget.
Fully enclosed pure Japanese schools are rare in China, because they are limited by venues, funds, manpower, students and teachers. I recommend full-time Japanese for iBS in Zhuhai, eliminate external interference, and advocate comprehensive and systematic listening, speaking, reading and writing training.
Language learning is most afraid of fragmented learning, because it will easily lead to "forgetting to learn, forgetting to learn" and no gain. If it is a full-time school, it will also help us monitor the learning progress.
