No, you can only pay by cash or credit card. Alipay is not available overseas.
Some stores can use the UnionPay system, while others can only use Visa or Master.
Personal experience, using a credit card costs a lot of money. In fact, the exchange rate at that time was 7.2, so anything I bought with my card was discounted to around 7.5. and it was not practical to carry too much cash
