No e-commerce platform can guarantee 100% authenticity. The quality of many big-name products in JD.COM Mall can be guaranteed, and so can JD.COM. COM's self-operated products are also genuine. Vipshop is mainly reserved for women, including shoes, clothes and bags.
If you want to buy electrical appliances or books, 3C products are better in JD.COM. If you want to buy clothes, especially brand clothes, Vipshop will be better. However, unlike JD.COM, you can search according to your needs. Shopping there is not targeted, so you can buy anything you see.
JD.COM publicizes that there are no fakes, and some self-operated goods from JD.COM can be delivered to you in the morning and afternoon, which is great! But I don't know if there are any fakes, but so far I haven't bought any fakes in JD.COM.
Brand clothing at the Expo is also clearance. Of course, there are many cost-effective clothes that can also protect consumers.
