Yang Anxing, 47, touches a bandage on his face in North China's Tianjin on Aug 14, 2015.

"I was having a rest at the construction site's portable house when I heard a sudden explosion. I climbed down from the second floor to save my wife. The second explosion came soon, Soon comes the second explosion, the portable house collapsed and my wife and I were hit and found ourselves covered in blood. My wife was hurt more seriously than I, and she is now under treatment at Tianjin Fifth Center Hospital and still can't open her eyes", said Yang, a migrant worker from Southwest China's Sichuan province.
