The "Learn Chinese with Mulan" language learning winter camp is an online learning project for children's Chinese and based on their psychological development and language acquisition laws. With the children whose mother tongue is not Chinese as the teaching object, and with the help of Mulan's story, we integrated the knowledge of nature, painting and other disciplines and the Chinese culture that students enjoy listening, watching and speaking. We encourage students to communicate their feelings in Chinese and feel the cross-cultural charm in many ways. This winter camp will make full use of learning resources, integrate multiple teaching methods, and focus on helping students acquire basic Chinese and master Chinese learning methods in activities.
