If you like to break things when you are unhappy, the Nanjing Zhonghua Middle School is the school for you. This term, Nanjing Zhonghua Middle School will build a "stress wall" to help students who feel unhappy because of schoolwork or for other reasons.

Tao Dehua, a leader at the school said the idea of a stress wall started when footprints were found on some newly painted walls and some school windows were broken.

"These things happen because some students feel lots of pressure from their studies or because they don't get along well with other students. When under stress, the body get ready to either run or fight and becomes very nervous. Hitting the wall can help relax the body and take away stress," Tao said.

"Tests and homework make me Sad," said Lu Yan, a junior girl. “I can't wait to hit the wall. It will help me a lot with my problems." 

Another girl student who wouldn't give her name said that the wall won't help. “Mainly because it can't talk," she said. "I need to talk to someone when I'm sad."
