ZHUHAI: Chen Weiquan, a 21-year-old migrant worker from Hunan province, started living an "extremely lonely" life after he came to work as a production line operator at a factory in the Qingxin industrial park this year.

"I have no friends or relatives to talk to. And all the workers at the factory made fun of me because I'm short," Chen said.

Often the migrant worker would sleep in the factory's dormitory for fear of returning to his camp where he would be laughed at.
