HeSi was born in 1962 in Beijing China and from an early age she demonstrated an exceptional ability to draw and paint. In her early teens she was trained by various Chinese masters including Zhang Wen-Xin.

In 1986, HeSi earned a degree at the Central Academy of Art and Design and eventually a position as an Associate Professor of Fine Art at the Central University of Nationalities. During her teaching years, HeSi produced surrealistic and naturalistic ceramic figurines. Their unique qualities and design reflected the essence of the earth that produced the natural material she used.

Moving to New Mexico in 1992, southwest art and especially the work of Georgia O'Keefe had a profound impact on HeSi's insight and her desire to express herself through the mystery and the beauty of Mother Nature.

After moving to California in 1995, HeSi and devoted her energy towards painting images of flower blossoms, in particular focusing on irises. Her attention to detail in these super-realistic paintings is uncompromising, and the results are stunning. Her Irises not only lead one to appreciate the wonder of nature, but they also encourage us to contemplate the human condition. She captures the energetic forces within each iris through the veins and the skin of each petal in a way that conveys to all of us the desire to live life to the fullest, with love beauty and passion. She says, "Irises show more facial expressions and emotions than any other flower."”

Her works are exhibited in collection in China, Japan, United States, France, Singapore and Hong Kong.
