Shang lost two sons in the earthquake. Shang tells others that she has four children, and two are not by her side. Before the earthquake, the lively two sons created a happy life for the family that neighbors admired in Yingxiu. Now the daughter and the son also have brought joy. Shang said whether the children are good in studies or not is not as important as leading a safe and healthy life.
