As a non-formalist, Liu cares for using symbols, implications, and unique cultural symbols to construct his images. With an Oriental mock and humor, he presents the depth, complexity, and uniqueness of human psyche, and with a playful intrusion in history and a reconstruction of dance, he gives birth to an absurd bizarre image similar with Alice in Wonderland. The mixture of the touch and colour as well as the extravagant setting of the background, his works imply dancing and the delight of distortion and indulgence.

Liu is good at picturing the absurd beauty of the urban dream. The colourful and variable images show the different experiences in real society. The characters appear in a world between the real and the unreal, and the quiet picture seems to foreshadow the coming of the unknown. Like the character in the picture with his eyes shut, in a seeming quietness the thought flows and implies countless possibilities of mystery, absurdity, or even danger. "Perhaps absurdity is the best way for modern people to be themselves in the crevices. In absurdity there is the sensation and beauty you desire, and the inner quietness you have dared not to beseech." Said Liu. Behind the absurd urban scenery in his picture, the rich symbol-like colour hints the happiness and peace inside the character as well as the richness and profundity behind such peace. Standing in front of his painting and gazing at the vastness of colour, you can only feel the touch inside your heart.

Meg Maggio, an American curator who has been familiar with the Chinese contemporary art, commented, "Liu is a promising young artist. His works reflect familiar characters and personalities out of the life of Beijing, and the painted characters present the hope and despair in an advancing Chinese urban life, with their inactive, repressing, and sometimes strange countenances."
