Yaya is how we call grandpa in Shanghainese （Chinese local dialect) and it is also the way how I call my grandpa in daily life. My grandpa was born in 1938 in China, and he has suffered from second-degree burn for 50 years due to the chemical plant explosion. This tragedy has become the scar and disability permanently imprinted on his body and hands. However, his tenacious vitality and positive attitude towards life has impressed me a lot. I live with my grandpa since I was born, so I spent most of my life with my grandpa than anyone else in my family. My grandpa was a pilot when he was young and he was assigned to the chemical plant by the Chinese government in 1970. And then the tragedy was happened in 1971. His face and body have been totally changed since then. When I stay with my grandpa, I never feel that he is different from others. He is good at so many things, repair, painting, drawing, playing the instruments and operating the remote control helicopter even if there are only two fingers can move on both of his hands. So, I decided to make a series of my grandpa to express his life not only as a disabled man but also as my great grandpa.
