The second-hand goods trade in China originated in the early 1990s. At that time, the old city was rebuilt, and many city people moved into new houses. At that time, there was nowhere to buy old furniture and old electrical appliances, and the second-hand goods market was born. Because of the relatively low price, migrant workers, urban low-income people and individual industrial and commercial households have become the main buyers in the market, and a number of second-hand shops such as high photographic equipment firms have become well-known in various cities.
