The international classical ballet courses, arranged by MCI (Maine Central Institute, USA), lasted for five days, and the class time was 90 minutes per day. In the courses, the MCI teacher Natalya Getman explained the movements first, and then the teaching assistant Jane demonstrated. After the ZZSH dance students were familiar with the movements, they practiced dancing in groups to music. Natalya observed the students' blind spots in the dance through Google Meet, and immediately explained and demonstrated for the students to follow, with the dance program coordinator Ms. Chunying Liu assisting and guiding her students on the spot. At the end of the course, Natalya stated that she was very proud to see the students’ remarkable progress during this period. She was very touched and looked forward to the next course session with the ZZSH students.
