Painting is a meditative process, which is a process of self-precipitation and healing. By combining the precise and meticulous gongbi technique (traditional delineative painting) and the depiction of modern subjects to convey her personal feelings, there is a sentimental quality in her modernized ink paintings. Cheng uses linear lines to define the subject forms in her stories; applies ink washes to render layers of feelings and varies the shades of colours to empower the expression of emotions. She creates her own visual vocabulary for expression of feelings, presenting a trinity of harmony formed by contemplative ink strokes, pastel shades and modulating lines.
