    What did the China's “New Four Great Inventions” bring to us？

    High-speed rail—Modern transportation makes everybody neighbors. The invention of the high-speed railway makes it easy to thousands of miles a day. Today China's rail transit technology is the best, the China's daily average of 4, 000 trains, sending about 4.6 million passengers.

    Shared bike—Short walks become more convenient and faster, and carbon missions are reduced, which is friendly to the environment. You can download the APP about shared bikes, pay some money, then you can use bicycles everywhere in the street. The Chinese shared bicycle programs have been becoming more and more popular.

    Online shopping—Don't need to go out to find the needs for living. Online shopping, as the name implies, is to pay money online. Purchases(购买物) can be sent home. China has 751 million internet users, 724 million mobile phone users; total transactions (销售额) on November 11 and December 12 hit a record high every year. Online shopping lets Chinese internet users enjoy “shopping carnival” every day.

    Alipay—A software which can replace cash payment. With intelligence phones' popularization, AliPay has become an indispensable (不可或缺的) APP. Through scanning the “QR code”, AliPay wants to realize the ambition of “replacing cash payments” gradually. On 11 November 2018, both the mobile payment account and the transaction reached 213.5 billion.

    There is no doubt that China has already used its own power of “New Four Great Inventions” to become the great powerful technological country, showing the power of China once again.
