Why are giant pandas called national treasures?

The giant panda is a rare and precious animal. It only lives in Sichuan, China.

The giant panda is cute and naive. Looking slow and stupid, sitting there eating bamboo, everyone feels particularly cute. Moreover, the reproductive rate of giant pandas is also very low, which is even more precious. The giant panda is now called the treasure of friendly exchanges between China and foreign countries. So it is called a national treasure.
