Family evacuated as threat looms

At the age of 4, my daughter has become an environmental refugee.

To escape the heavy smog that started to blanket the capital city late Monday, my mother-in-law, 63, and my little girl, accompanied by my husband, boarded the train early Tuesday morning for my hometown of Nanjing, an eastern city about 1,000 kilometers away.

Unlike traditional tragic refugee trips, the journey was a happy one. Having no idea of all the possible hazards that smog could cause to her, my daughter appeared very chirpy at the railway station for being able to skip kindergarten for a few days, and in Nanjing, she could see her beloved grandmother.
