China, which has Four Great Inventions（发明）in ancient times, has again showed its ability to change the world with its “ new four great inventions”. The four new ways of life are the most popular among young foreigners who study and work in China.
●Electronic payment （电子支付）
“My wallet is no longer in use. I can buy and eat whatever I want with a tap of fingertip on my phone,” said Lin Jinlong, a student from Cambodia（柬埔寨）in China. “Even pancake sellers are using Alipay mobile payment. ”
●Online shopping
“I can order food online at home. This is super convenient （方便的）. If I am at home in Cambodia, I have to go outdoors. ” China is innovating （创新）and no longer copying Western ideas. China has the largest mobile phone use in the world. This makes online shopping much easier.
●Shared bicycles
Shared bikes bring cycling back to people's lives and make public transport more popular. The bikes themselves aren't new, but China has made the world surprised with the operating model（运营模式）of bike-sharing.
●High-speed railways
Lin talked about his experience of travelling by Chinese high-speed train from Beijing to Tianjin. The journey takes only half an hour, while in Cambodia, which has only two railways, such a journey may take up to three hours.
