Although China is a developing country, the country has developed rapidly in recent decades and has made considerable progress in technology and production. Some Chinese science and technology are even at the leading level in the world. These technologies have played a very important role in the convenience of the country and the development of mankind. Among them, China’s five leading technologies in the world are:

1. Superb bridge construction technology

We all know that China has the title of “infrastructure madman”, especially in the technology of bridge construction, it is even at the world’s leading level. Among the world’s ten largest sea-crossing bridges, China occupies 5 of them. In Gaoqiao, China accounted for 71. In particular, the Hong Kong-Zhuhai-Macao Bridge, which opened to traffic in 2018, has the longest mileage, the longest undersea tunnel, the highest technical content, the most difficult construction, and the most scientific patents in the world.

2.The world’s leading high-speed rail technology

Decades ago, most of the world’s high-speed rail technology was in the hands of Germany and Japan. At that time, we were looked down upon, thinking that China would never build our own high-speed rail. In the following decades of development, China used its own science and technology to build our own high-speed rail through independent research. At present, China’s high-speed rail has its own unique set of high-speed rail technology modules, and has independently developed and manufactured the “Harmony” with a speed of 300 to 350 kilometers per hour. my country’s high-speed rail is in a leading position in the world in terms of railway network lines, operational safety, operating speed, and operating efficiency. Now it has the world’s most advanced high-speed rail technology.

3.5G communication technology

Everyone knows that 5G is 100 times faster than 4G. This also shows that the advent of the 5G era will change the world’s technology. The only countries that can have this technology are China’s Huawei and Qualcomm. With 11,423 patents, Huawei ranks first in the world. Huawei is undoubtedly the best and most prominent company among my country’s current technology companies. It can be said to be China’s hope in the field of 5G technology. At present, Huawei’s 5G technology is more prominent and stronger than Qualcomm in the United States, so the United States has always been worried about the rise of China’s 5G communication technology.

4.AC/DC UHV technology

At present in my country, UHV refers to the voltage levels of AC 1000kV and DC ±800kV. Internationally, UHV usually refers to voltages of 1000kV and above. my country’s UHV technology has the characteristics of long distance, low loss, and large transmission capacity. At present, the power grids in the world are mainly based on 500 kV AC and 500 kV DC. The ±800 kV UHV DC transmission technology independently designed and developed by China is the DC transmission project with the highest voltage level, the longest transmission distance, and the largest transmission capacity in the world. It has completely independent intellectual property rights and AC transmission technology.

5.Mobile payment

China is currently the most convenient country for payment. No matter where you are in China, you can carry out transactions as long as you bring a mobile phone. This is obviously integrated into our daily lives. But the various basic communication facilities behind this are very, very large projects that other countries can only catch up with.
