Both he and Wang are good at drawing plum blossoms, and some have their own interests. Jin Nong once said that the plum blossoms in Gao Xiang's works are "as thin as herons standing cold and unwilling to play near."

The figure painting style is high, and the rocks are often painted with "pockmarked skin", with just right moss spots, few renderings, concise brushwork, elegant ink color and ethereal feeling. Trunk often uses double hook technique, leaves are round or dots, and the ink color is clear and moist. He is a student of Shi Tao, but his paintings are different from Shi Tao's. His paintings have a strong personality, which is the embodiment of Shi Tao's "learning from nature and using my method". Gao Xiang is good at landscapes, figures, flowers and birds, calligraphy and so on. People can increase their understanding of Yangzhou Eight Eccentrics through his works. Sometimes the state of collection is not reflected in economic value, but a period of history and a period of culture. At present, Gao Xiang's original works rarely appear in auctions, and the auction price is about RMB-0/00000 per square foot/kloc, but the value is still higher than the price. This is mainly caused by Gao Xiang's few works and only a few experts and scholars know him. Gao Xiang is an important figure among the Eight Eccentrics in Yangzhou, and the Eight Eccentrics in Yangzhou is also an important painting school with far-reaching influence. His paintings are well worth collecting.
