The theme of this activity is “Entering Changchun-a city of film and motor, experiencing the real life of high school students”. It is carried out in the forms of live online Chinese class, recorded theme class, cloud demonstration class, online cloud travel experience and online communication. This activity aims to let Lesotho students feel the cultural atmosphere of Changchun, the snow, ice and food culture of Northeast China, and understand the real campus life of Chinese high school students. The activity enables Chinese language learners to not only understand the Chinese language and culture, but also get to know the status quo of Chinese basic education, Changchun, China, and Chinese traditional culture. Carrying out “Chinese Bridge” online communication project is the important approach to the three-dimensional international development strategy of our school, and an important platform to promote the development of the Confucius Classroom of our African Lesotho Renowned International School. It is hoped that the following objectives can be achieved through the exchange activities: First of all, the students in the Confucius Classroom in Lesotho, Africa, will learn about the culture represented by Changchun in Jilin Province, and learn about the history of Changchun's representative enterprises -- FAW Factory, Hongqi development history and Changying Studio through live and recorded courses so as to have a better understanding of the culture of China's automobile manufacturing industry and film production industry and increase the country's reputation. At the same time, students will experience the ice culture of China through the regional characteristics of Changchun. Secondly, it aims to let overseas students know the real situation of Chinese high school students, understand the development status of Chinese education and the application of Chinese modern technology in the campus, perceive China's modernization development, and promote overseas talents to study in China exchange. Third, it is hoped that young people around the world can learn about China and connect with the world through the "Chinese Bridge" project.
