The period from 2012 to 2020 is a decade of rapid economic development in China and a decade of deepening friendship between China and Latin America. It is particularly important for all Chinese learners who undertake the mission of cultural communication to understand the development of China in this decade and its significance for other countries in the world. This online group project focuses on five themes: environmental protection, transportation, rural education, people's daily life, and China Latin America exchanges. It shows students the changes in all aspects of China in the past decade and the deepening of exchanges between China and Latin America. It leads the online discussion of global youth to jointly think about the challenges facing world peace and development and the responsibilities of youth.
