The owner of this shop is an old master. There is a patent certificate and a national award certificate for his invention in the counter. The service attitude is not very enthusiastic. I can understand it myself as a technician. The technology is really superb. I accidentally broke a pair of Montblanc glasses frames brought back from abroad, and the specialty store could not repair them. The only way is to change the frame, which is not available in China. Buy a bottle of potions once in a while to get to know them. The old master once designed clocks and watches. He participated in the design of the first self-made electronic watch in Shanghai. He said that my frame could be repaired, and he quoted a price from 300 yuan, which I found acceptable. I also had the idea of giving it a try. He said it would take a week, and he made the parts himself. After a week, I saw that my glasses had been repaired, and the scars were well repaired. Later I started chatting and learned a lot. This old master specializes in repairing watches and glasses that cannot be repaired outside. It used to be the first signboard of Shanghai Watch and Glasses Maintenance Center. On the other hand, Old Master Q has a hard temper. Later, I took some antique watches from home and repaired them for him one after another. I repaired all the watches that Haendly said could not be repaired. I am very happy. Thanks to the master, it really showed me that the mountain is not high, but there are immortals. In fact, the old master has been met by the municipal leaders, and so has the appraisal annex of the vocational training appraisal institution of Shanghai Labor Bureau.
