Routine work for Zheng at the chemical plant includes cutting long plastic pipes into short products. Although the acrid smell of the pipes made her feel terrible, she persisted in working there for the 1700-yuan wage. However, her physical condition began to change and her nose kept bleeding. A lump came out of her ear after two-months of working at the company. She had no strength to do her job anymore and decided to return home to recuperate. [Photo: weibo.com]
