In the early nineties, Diao began to incorporate biographical elements that include his own career histories, as well as themes of his Chinese heritage, emigration, and displacement. In 1979, the year when the Sino-US diplomatic relations established, Diao went back to China and for the first time after 30 years, he saw his mother, who gave him his maternal Grandfather's book. However, the artist did not use silkscreen printing to present a few pages of the book on this painting until 2017. Diao's grandfather Changheng Yin was an important figure in bringing down the Qing dynasty. After studying abroad in Japan, he returned to China and was appointed as the Land Force Fast-paced Training School principal. He later became Minister of War for Sichuan military government, quelling the revolt for independence on the part of the Tibetans.
