Painful search for reunion

Xing's life hit the bottom after she lost her son and husband. She got married again but hasn't stoped looking for her son. She is the owner of a bookstand in Zhengzhou. When Dong Lin went missing, she was selling books at the market. Xing doesn't want to give the the business up even though she can barely make money from it.
