Ping Shen has lived in Hong Kong for 37 years. He has been active in the painting world. As the vice chairman of the Hong Kong Painters Association, he teaches and creates. Last time I first saw his solo exhibition of watercolors, I saw a big difference. I went around the gallery a few times and repeated the exhibits, and found that he was not only good at watercolor, but also good at prints, ink, and maybe oil paintings. Such a versatile painter should look at it differently, and it is not appropriate to view it in general.
