●Recently, the medals of the 2022 Beijing Winter Olympic and Paralympic Winter Games were accepted in Shanghai. According to Shanghai Mint Co., Ltd., a medal needs to go through 18 production processes and 20 quality inspections. One of the most difficult problems is the use of the traditional goldworking polishing technique of the gold medal, and a gold medal pressing requires a grinding master to work under the microscope for 8 hours to complete.
