Wang Xiaojun is 12 years old. He lives in the country in Gansu Province. Today is his birthday. His parents prepare a nice dinner for him, but the boy says, “I won’t have the dinner because after the dinner, today is over, and you are leaving for Shenzhen tomorrow. I don’t want to let you go.” It is the first birthday that Wang Xinojun is spending with his parents during the three years. In the past three years, his parents have stayed in Shenzhen and worked to make money. They haven’t seen their son for three years. Tomorrow, they will have to leave home to go to Shenzhen again. Wang is not the only stay-at-home child. There are more than 20 million stay-at-home children facing a lot of problems. Many of them stay with their grandparents. They get less care from their parents. Their parents can’t help them with their studies. The Chinese government now cares about the children very much and is trying to solve their problems.
