"At the Seaside, Long Ago" is a painting of the artist and his wife by the seaside. The beach and the sea are joined as one; this coupled with the blue coloration of the artist's clothing, creates a sense of peace and serenity, of harmony, and of permanence. Cheng's wife is depicted holding his arm; both figures are shown facing forwards, relaxed, carefree, and engrossed in one another, making the painting a record of a joyous, unforgettable relationship. The gray-green mountains behind the beach extend far into the distance, strengthening the sense of depth that the painting creates. The patch of red flame in the middle distance, with smoke rising up into the heavens, is a striking touch that draws the viewer's attention, and brings to mind the idea that someone may be camping on the beach."
