范文：

The four new inventions

China is an old country with a long history and great inventions. With the development of technology, the country boasts of four new inventions: Ali pay, shared bikes, shopping online, and high-speed trains. Among them, I like Ali pay best.

First of all, Ali pay is convenient for shopping. When we go shopping, we do not have to take much cash with us; instead, we can just scan the code on our smart phone. More interestingly, we can join the “red envelope war” by touching the screen of our smart phone on the Chinese New Year's Eve.

Do you like Ali pay? Just experience it by using your smart phone to buy something.
