As we all know, great changes have taken place over the past years in China. People's living conditions have improved a lot. The environment around us has become better. We are getting used to travelling by high-speed train because it's easy and fast. Online shopping has been more and more popular. Even my grandparents have learnt how to shop online.
Among all the changes, I think mobile payment is the most surprising. Now we don't need to take paper money or wallets with us. We can pay for nearly anything with our phones. Isn't it amazing?
