You can first publish your purchase information on the second-hand furniture network in Chengdu, and by the way, you can also browse whether the products released by others meet your requirements. In addition to the second-hand market you know above, there is also a second-hand resource market in Jinjiang District, where the goods are quite neat. You can have a look, and then take the No.805 bus at the tea shop.
If the price of second-hand products is too high, I suggest you go to Bayi furniture market, where there are many styles and cheap prices. If you are lucky, you may encounter a backlog of products, which will be good and cheap. Ha ha, friend, good luck!
