He reproduced the painting in 1960, with a few changes, for the capital Military Museum of the Chinese People's Revolution.

Li's output includes not only iconic works reflecting the country's revolutionary course in the 20th century, but also portraits showing his concern for people at the grassroots and landscapes displaying poetic refinement.

Li was born in Vietnam to a Chinese father, who migrated from South China's Guangdong province to work in the coal mines in Hongay, a port city in Vietnam, and later married a Vietnamese woman.
