Generally, in Chongqing, like the 6070 shopping mall in Chongqing in the new century, the postman is 4 19. I can't explain online shopping clearly. There are good ones and bad ones. If you want to buy online, you'd better choose a guaranteed website. Personally, I think you can still say that Suning.com is ok. You have to watch anyway. You have to have an official invoice. Only invoices can guarantee the quality of goods, and you can also carry out a two-year free warranty.
