Closure has nothing to do with geographical location, but is directly related to language environment. For language learning, what matters is not the big environment, but the small environment. Adapt to the small English environment and gradually transition to the big English environment, step by step, which may be the real process of "learning" English.

The closed English training school allows students to immerse themselves in the English environment all day, which is relatively closed. Food, clothing, housing and transportation should be fixed in one area, and the time is relatively stable, which is conducive to the formation of English thinking in a short time. During studying iBS in Zhuhai, students are immersed in the world of pure English all day, away from the interference of life and work, and only concentrate on learning English.

There are not many closed English training schools in China, because they are limited by venues, funds, manpower, students and teachers. Large-scale full-time schools generally have independent teaching buildings, dormitories, canteens, sports fields and other enough space for students to study and live, and eat, live and travel together. Let learners have no worries.
