The well-known "new great inventions" of modern China have made our daily lives more convenient.

High-speed trains

China created its first high-speed railway line in 2008. Since then, the number of passenger trips has grown by over 30 per cent every year. By 2016, more than 5 billion trips had been taken on the trains. By 2020, one-fifth of the country's 150,000 km railway network had been used by the trains. This network links more than 80 percent of the major cities across China.

Mobile payment

Mobile payment is turning China into a "cashless society". Instead of paying by cash (现金), customers now pay for their goods and some kinds of bills simply by typing a short password into the Alipay or WeChat app on their mobile phone.

Shared bikes

China has surprised the world with how quickly shared bikes are widely used. Nowadays, bike users can simply pick up or park the bikes on the street through GPS and smart phone apps. China's two leading bike-sharing companies, Mobike and Ofo, have been opening their overseas markets in Singapore, the UK and the USA.

Online shopping

With around 751 million Internet users, China has been the world's largest and fastest-growing online shopping market. Because of lower costs and fewer licensing requirements(执照要求), it's easier for sellers to open an online shop in China. In 2016, more than 20 million jobs of rural areas were created, with over 8. 1 million running their own online shops.
