1. We bought a computer at Lenovo Han Hui authorized store, a third-party store in JD.COM, and we found that this store was not reliable. Not only can you find the dishonest behavior of the store on Baidu, but most of the bad reviews are about this kind of computer. Many complaint merchants have replaced the original hardware of computers with unknown hardware, reflecting the frequent problems and poor after-sales service in used computers.
