It was one example of the role that Tianma has played in international coordinated

observations. Its super sensitivity has made its observations useful as a reference by which other parti

“Tianma elevated the image quality of the EAVN, by about 50 percent, making a great co

nt for Chinese people because of the rapid development of high-speed trains and the civil aviation industry, the transfer

from one mode of transport to another can still be troublesome at times. For instance, some high-speed train stati

ons have been built far away from the cities they serve, dragging down travel efficiency.

And third, some practices-such as free highway passage-may aggravate the conflict between supply and demand.

To solve these problems, which could worsen during holidays, synchronized planning and cooperation of multiple departmen

ts are required. To cope with holiday traffic, the authorities should also promote smart transportation and use a

dvanced technologies including artificial intelligence and big data to improve travel efficiency.

mobile phones, consumers are able to talk with overseas buyers, which will greatly enhance users’ trust on the platform.”

China’s cross-border e-commerce sector has been growing rapid

ly over the past few years, owing to a rapid growth in the nation’s middle and high-income shoppers.
