Master Wang Jin, a 55-year-old "network celebrity", is the third generation inheritor of the national intangible cultural heritage and has worked in the Forbidden City for 39 years. Every day from eight to five, sitting in the office for a day, for decades, dealing with cultural relics that have been dusty for many years. When the watch to be repaired arrives, you need to take photos first and make a maintenance plan. After disassembly, cleaning, matching, assembly and debugging, it can be stored in the warehouse until it works normally. Master Wang has a "post-80s" apprentice, Qi Haonan, who studied with his master for 10 years.

Wang Jin said that unlike other cultural relics restoration, the most unique thing about clock restoration is that "the watch can move and turn, which is called restoration." Qi Weinan told reporters that the biggest headache in the work is to encounter soft problems-all the processes have been completed, but they just can't be installed. This must be dismantled and rechecked. Sometimes a small problem can be pondered for days. Master Wang and Qi Haonan have been to the Dutch National Music Museum and the British Museum for live exchange. Qi Haonan said: "Compared with foreign clock repair, our advantage is excellent basic skills and solid practical experience, while foreign countries rely more on machine repair;" There are special watch repair schools abroad to carry out systematic teaching. At present, we basically have no related majors. "

Talking about the future development, Master Wang said: "The craftsmanship handed down by our ancestors cannot be broken. If possible, I will try my best to help new young people get in touch with overseas study opportunities. There are more than 1000 clocks and watches in the Forbidden City, and it takes generations to repair them. Even if it is repaired in a day, regular maintenance requires a lot of work. This is a cyclical process. "
