Sang Huoyao’s calligraphy is worth collecting. Sang Huoyao's works are innovations based on tradition, which are contemporary and modern. The paintings are thoughtful, ethereal, spacious, with a sense of space and tension. Paintings have a dimensional space, a sense of time and space, which expands the artistic space and leaves people with a lot of imagination. Each painting is different, and it can be seen that it has been carefully conceived and painted just like that. Some people always paint one form or subject without exploring it. What’s the point of painting the same painting all the time? Every painting has an idea and is different, so this is the right thing to do. Every moment feels different, so each painting should have a different feeling.
