Dr Choong was very much inspired and influenced by the Abstract Expressionism, a major art movement in the US during his stay in New York form 1965 to 1969. As a result, he produced a series of abstract ink paintings by employing, exploring and exploiting the techniques and knowledge of conventional Chinese ink painting he learned during his study in Taiwan. In this series, the forms and shapes are liberated, integrated and became mere strokes, textures, forms, tones and shades. Bold strokes are vividly dancing and interacting on the paper. Tones and shades of ink are permeating, running, expanding and penetrating which further generate visual dynamics.

1965 至 1969 年间锺博士在纽约留学时，极受当时美国流行的抽象表现派的鼓动和影响，而完成这一系列的水墨画。表现手法接近抽象表现派。他把在台湾师范大学深造时从黄君璧，林玉山及溥心畲等老师所学到的传统中国画技法和知识，予以深化发挥，並以抽象表现的手法完成这一系列的水墨作品。粗旷笔触，交织舞动于紙上，墨韵和色调的渗透，流动，扩张和交融是這一系列的创作的特征。
