Closed full-time course is an immersive, closed and pure foreign language training method, which enables a zero-based student to reach the professional level of applying foreign languages within one year. The foreign language you learn is the only one allowed. Regardless of class or rest, activities or meals, students and teachers in closed classes must communicate in foreign languages to simulate a truly closed and pure foreign language living and learning environment.

It provides a completely closed and pure foreign language environment for learners, and creates a good language learning model. All courses are taught directly by relevant professional textbooks, helping students to try to form the habit of thinking in a foreign language from the beginning. Teachers use various methods other than translation to help students teach intuitively through behaviors, pictures, sketches and facial expressions, so as to integrate life and entertainment and give full play to students' subjective initiative. Both beginners and learners with a good foreign language foundation will completely forget that they are learning in a pure language environment, and subtly achieve the goal of training language application skills and improving listening comprehension.
