Extremely fast land travel

By the end of 2010, high-speed railways were still unfamiliar to ordinary people. But now, the travel time between Beijing and Guangzhou has been cut to only 10 hours, down from more than 20 hours in the past.

By the end of 2015, the operation mileage of China's high-speed rail had reached 19,000 kilometers, ranking first in the world. China has become one of few countries to boast complete high-speed rail technology.

Only a few developed countries have comparable labs.
