Aang Jiancuo, 46, is the inheritor of the De'ang Sazhi Tibetan Calligraphy, which has been listed as the national intangible culture heritage of China. The inheritor learned the calligraphy by himself at the age of 12 and followed Bazhi, the seventh heir of De'ang Sazhi Calligraphy from 27 years old. Currently, the 46-year-old craftsman is teaching the heritage to 152 students who come from Qinghai, Beijing, capital of China, East China's Shanghai and Southwest China's Sichuan. "To protect this cultural heritage is my lifelong dream and I would teach anyone who like to learn it," said Aang Jiancuo.
