China’s total freshwater resources are 2.8 trillion cubic meters, accounting for 6% of global water resources, second only to Brazil, Russia and Canada, ranking the fourth in the world.

This is not an alarmist objective reality. Since the 1980s, the water shortage in China has gradually spread from the local area to the whole country. The situation is getting worse and worse.
