In 2000, Deng continued his study at Tsinghua University's Academy of Arts and Design in Beijing, where he took up jianbi (minimal brush strokes) in ink art as his painting style. The painting method dates back to Liang Kai, a Song Dynasty (960-1279) court painter. The art style uses bold lines, abbreviated brushwork and dynamic imagery to reveal the essence of a subject.

In 2015, his solo exhibition entitled The 20-year Retrospective was held in Shenyang. Last year, his exhibition was held at the Luxun Academy of Fine Arts.

Deng wanted to make his contribution through painting during the COVID-19 outbreak in China. He created two paintings in January, which were donated to online auctions, and the earnings went to the Wuhan Charity Federation to help in the fight against the virus. His painting videos have been viewed tens of millions of times online.

Deng says the interactive experience for viewers in participating in a painting process will be highlighted, making art appreciation more dynamic in coming times.
