Can I use other people's papers to buy duty-free things in Sanya?

What you want to ask is, can I pay for duty-free shopping in Sanya with other people's coupons? You can't use other people's coupons, but you can pay with other people's.

According to the shopping regulations of Sanya Duty Free Shop, shopping vouchers can only be used if I have the corresponding identity documents and ticket information, and I have to check them on the spot, so I can't use other people's vouchers to buy things in the duty free shop.

But you can give what you want to buy to others and let them pay together, so you can also use coupons and transfer the money you bought to him after payment.
