The location of Shiqiaopu in Chongqing is basically a profiteer selling computers. Although I haven't been anywhere, many netizens are from Chongqing, and many of them have been cheated. Therefore, Xiao Bai had better not go to a physical store to buy, and people who know computers need to be careful when they go. The profiteers will sell second-hand goods as new ones, and they won't give you a warranty if they buy them. It's best to buy hardware online and ask someone to install it.
