Recently, the first urban track in Hanoi, Vietnam, the Jiling-Hedong line transportation project successfully completed the power supply, and the smooth opening is just around the corner. This urban rail transit project is not only built by China, but also fully designed and constructed adopting Chinese standards. At the same time, under the Chinese standards, there are also the Astana Light Rail Project in Kazakhstan and the Tel Aviv Red Line Light Rail Operation and Maintenance Project... With the accelerated pace of overseas construction of Chinese companies, not only the “hard work” built by China has gone abroad. "Soft power" such as China's standards and China's services are also sailing to abroad, contributing to the construction of the world, especially to the "Belt and Road ".
