We encourage students to sign up for several courses with different teachers, stay with the teachers for at least 2 to 3 years (4 to 6 semesters) and learn more about the teacher’s country and ethics through life experience sharing, cultural exploration, and even his or her personality, religion, or educational background. Why does the teacher devote himself or herself to this profession? What is the factor that appeals to them to dedicate decades in a field? Where is their hometown on the map? What is the daily food they eat? What festivals do they celebrate? What is their traditional clothing? What currency do they use? Curiosity makes young kids learn new things when learning is such an amazing activity like making friends with whom have many differences to share with rather than doing the boring routine to memorize some content in the textbooks. We try to build up students' international vision besides learning some knowledge or skills in class.
