There is no uniform standard in the whole country. Zhou Shengsheng, Chow Tai Fook, Luk Fook Jewellery and Laomiao Gold all said that "trade-in" must be charged with depreciation, which includes not only the loss of recasting, but also the working hours. At present, there is no unified industry standard for depreciation and working hours in China, and each brand dealer independently formulates relevant standards.
