HANGZHOU - For the children of Chinese migrant workers, millions of whom have moved their families to the country's biggest cities to seek employment, life can be lonely and difficult.

Wang Qi, the daughter of a migrant couple, wants to return to her hometown in east China's Zhejiang province, even though she has lived with her parents in the province's capital city of Hangzhou for more than two years.

"I miss my hometown. Everything is good here in the city, but I don't have any friends," said the 12-year-old girl. "I'm so lonely."
