Mou Changyou, 59 years old this year, is a senior cultural relic restorer in the protection and research room of the Maijishan Grottoes Art Research Institute. He has been engaged in cave cultural relic restoration work in the Maijishan Grottoes for 40 years. Mou Changyou still remembers when he looked up in his yard as a child and could see a mountain resembling a wheat stack - Maiji Mountain. It was from then on that Mou Changyou became interested in the statues and murals on Maiji Mountain. In 1985, a chance encounter led this young farmer to enter the Maijishan Grottoes, which he had admired for many years. Starting as a small worker mixing mud and delivering goods, Mou Changyou began his career at the Maijishan Grottoes Art Research Institute. The Maijishan Grottoes, located in Tianshui City, Gansu Province, were first excavated in the Later Qin Dynasty about 1600 years ago. It is named after its resemblance to a wheat stack and is one of the "Four Great Grottoes in China". There are 221 existing caves with a large number of exquisite sculptures and murals, known as the "Oriental Sculpture Exhibition Hall", which attracts many tourists to visit every year. In the Maijishan Grottoes, Mou often started by cleaning the grottoes and tidying up tools, and then worked for over ten years as a laborer for the master craftsmen, pounding mud, smashing soil, and kneading hemp ropes. He learned the craft through exposure and the master craftsmen's words and deeds, and used his rest time to read professional books, drill and study restoration techniques and processes. Gradually, Mou Chang completed his transformation from a farmer to a cultural relic restorer, and gained the opportunity to independently carry out restoration work. Forty years have passed, and Mou Chang's hands have caressed over twenty caves. He said he always feels like he doesn't have enough time, so he wants to make the most of it and do more. Whenever cultural relics are properly restored, he feels very satisfied in his heart. After years of honing, Mou Chang's skills in restoring cultural relics have become increasingly mature, and when faced with young people's inquiries, he generously imparts them. Statue murals are all frozen history, and guarding them requires patience and perseverance. We believe that young people can take over the baton well and make this precious human cultural heritage sustainable, "said Mou Changyou. (New Society)
