“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（柬埔察）in China. “Even pancake sellers are using Alipay mobile payment.”

Online shopping

“I can order food online at home. This is super convenient. 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.
