Large numbers of security guards quit their jobs every year because of low pay and a lack of training that restricts their chances of gaining promotion. Others suffer abuse and even violence from the public.

In an effort to reduce the number who leave, National People's Congress deputy Zhu Liangyu is calling for measures to improve their lives.

"My efforts are aimed at ensuring security guards get sufficient rewards and more protection, in the hope that the number leaving can be reduced," said Zhu, 42.
