Language expresses oneself, constructs ideas, and spreads civilization. Language flourishing is critical to the successful achievement of the Sustainable Development Goals in the United Nations 2030 Agenda for Sustainable Development. The "One Planet, One Future" series of character mini documentaries was officially released in early December, aiming to promote the integration of language learning and sustainable development through "Chinese + sustainable development", and stimulate people's interest in learning Chinese from a new perspective. Expand the understanding dimension of Chinese culture for Chinese learners around the world, and perceive the concepts and actions of contemporary China in the aspects of "humanities and art", "science and technology" and "sustainable future”.
