Taobao even started “online shopping festival”, the Double Eleven. It’s reported that Taobao and T-mall may have more than 800 million goods. Their company Alibaba has developed into the world’s largest ecommerce(电子商务) company. Bike sharing Bike sharing is not a new idea. But China has given it a whole new meaning. It encourages people to ride the public-sharing bike over short distances, aiming to solve the “last mile” problem in big cities. We use mobile apps or cards to unlock bikes. We can leave the shared bikes at any bike station. This makes bike sharing much easier. Cashless payment(无现金支付) In China, now you don’t need cash or bankcards to buy things. You could just pay with your mobile phone. You can scan(扫描) a store’s QR code(二维码) to pay. Even a fruit seller on the roadside has a QR code for WeChat Pay or Alipay. High-speed trains On September 21, China’s new high-speed train Fuxing made its first run from Beijing to Shanghai. It ran at a speed of 350 km/h. This makes it the fastest train in the world.

A Special Pizza Box The green box is a pizza box that can be used again. It makes less trash. There are four plates on the top half of the box. People don’t need extra paper plates. The bottom of the box folds in half and can be used to hold leftovers. William Walsh invented the green box. His friends often ate pizza, but they never used plates. One day, a friend got some hot cheese on his shirt. Walsh gave him a piece of the box to use as a plate. A Safer Fan The electric fan was invented more than 130 years ago. It has blades that spin and move the air. A company called Dyson has invented a new type of fan. It is safer to use it and it can be easily cleaned. A Living Wall How does your garden grow?
