"The goblins learned to make spring cakes at the beginning of spring, play chestnut cakes at the autumnal equinox, and make dumplings at the winter solstice..." a pair of dark eyes focused on the teacher who was telling a story on the podium for fear of missing a fragment. Recently, a public welfare group composed of five authors and editors of CITIC publishing house came to six schools, including CITIC Banpo hope primary school in Pingbian Miao Autonomous County, Yunnan Province and Dashan primary school in huangmaoling Township, Yuanyang County. In five days, it brought 16 vivid and interesting "dream classes" for children, including history, art, traditional culture and natural science popularization. Zeng Zirong, the author of "riding to see China" and "Chinese painting in color", took the horses in 12 famous historical paintings as clues to teach children a funny "art lesson on horseback". He also vividly analyzed idioms related to horses, such as "one horse takes the lead", "one horse misses the front step" and "one horse follows the lead". The teaching content integrates art class, history class and Chinese class, which is loved by children. Among the teachers, a teacher named Shan Qi is particularly special. Born in Yunnan, she has deep feelings for this land. She knows what the children here lack and need. In the manual course of natural science popularization carefully prepared for the students, Shan Qi started from the law of leaf color change, made leaf bookmarks together with the students, took the children to know plants and approached nature. Shan Qi said: "I hope this activity can ignite children's enthusiasm for learning natural knowledge, start from interest, and understand the broader world with the help of classroom and reading." This year is the third year that CITIC press has carried out public welfare activities in remote areas of Yunnan Province. Facing the children's question "will you come again", the author and editor participating in the activity firmly said: "you will come again." (outlook new era)
