Amazon's self-operated goods are more reliable, and the shopping experience on Amazon is particularly good. If you don't like the things you bought, you can return them within a month as long as it does not affect the secondary sale. Moreover, Amazon's couriers will come to your door to pick up the goods, so you don't need to send them back yourself.

Tmall is made up of individual merchants, and it is difficult to manage if they sell fake goods. Amazon's self-operated ones will be more secure.
