My name is Liu Yang, from Sichuan, 38 years old, graduated from junior high school, I am doing water and electricity installation at a construction site in Guangzhou. I am a real migrant worker. I have been married to my wife for 16 years. The couple has been together. She works in an electronics factory. She sits on the assembly line for 12 hours a day and is busy. She works very hard and her salary is so low. When she comes back, she complains about back pain all day long.
