The wall bricks are taken

for private use.

1/3 of the Great Wall has disappeared.

The length of the Great Wall is increasing due to new finds and renovations.The wall is becoming shorter and shorter day by day due to the natural erosion and human activity. Some people tore down the wall in the name of modern construction, or even took the bricks from the wall for private use. All of these actions brought large damage to the wall and many parts became unrecognizable. The implementation of the Protection Regulation since 2006 stops some human damage, but the length of the Great Wall has been inevitably shortened.
