manufacturers will not want these old household appliances, including accessories. The old household appliances exchanged by manufacturers are sold to the recycling market. In the recycling market, all the household appliances that can be repaired and used are sold to consumers in the form of second-hand. Some important parts that can be used after disassembly that cannot be repaired are sold to repair shops for reuse, and the parts that cannot be used are recycled by special recycling plants. The same is true of hawkers after recycling.
