My advice to you is that it is best to buy energy-saving lamp accessories in Guzhen, and just assemble them directly when you buy them (as long as the ballast and pipe pressure match, the quality is fine). As long as you buy from him, the merchant will tell you who makes money and who tries to help you. Sales channels are mainly around the hardware and electrical market and building materials wholesale market. It will be hard at first, but once the network is established, you will be relaxed.
