Hello, everyone. I am David from the US. After not visiting China for more than ten years, I am very surprised at the changes in China.
In China, online shopping is very popular, and mobile payment(移动支付)apps are becoming very important. Many people like using WeChat Pay and Alipay. They don't use cash(现金) any more. Both the young and the old use the mobile payment.
People can see OR codes(二维码) almost everywhere when they need to pay. They can just scan(扫描) the QR code to pay a bill. Some people from other countries have no WeChat Pay or Alipay, so they have to pay cash. But luckily, they don't need to wait long to pay because lots of Chinese use WeChat Pay or Alipay.
I am very interested in the mobile payment, so I download WeChat Pay and Alipay and learn how to use them from my Chinese friends. And now, I can pay anywhere and anytime, and my life in China becomes easy too!
