Sometimes I get messages from strangers in the message box.

Generally, if there is no threat in front of the link address, there will be a small green circle with a tick, which is something you can click to see and belongs to security. If it is a small circle with a yellow question mark, generally don't click it easily, so the link will be very dangerous.

Personally, I think it's useless to have that coupon. I used to have 20, 10 in 5 yuan, which exceeded 10. As a result, these are useless, because coupons must be used for goods marked with coupons. The seller raised the price almost before. On the surface, it was a few dollars cheaper, but in fact it was not cheap at all.

Finally, what is the safest way to trade Taobao?

Register Alipay, don't play remittance, Alipay is safer and more assured.
