Since 1999, every summer a group of Fudan students have been going to teach at San He Middle School in Xihaigu area, Ningxia, thousands of miles away. The documentary "The Supporting Teachers", created by Yinchuan Jufen Visual Creativity Co., Ltd, truly recorded the story among volunteer teachers and the children in Xihaigu, Ningxia.
There are 7 teaching buildings at Fudan University, but only six on the Shanghai campus. The "7th teaching building" is in the poor mountainous region of Ningxia, where a group of students volunteer to teach every year. Mr. Wu Heng's story began with a dictionary.
