"Zhao Xiaohai's artistic endeavour has much to do with the environment of contemporary China ink-wash painting. The vividness and impact of his Chinese landscape paintings have aroused deep curiosity and attention of art circle in China."
- Li Mingliu
"In the years under the tutelage of Prof Jia Youfu, a master in Chinese ink-wash painting, Zhao Xiaohai made a great effort in sketching from nature, besides learning from ancient masters, such as Gong Xian, by copying their works. I have seen those sketches, elaborate and in depth. As for creativity paintings, the high-and-far composition, undulating mountain and river scenes, the accumulative technique of chinese ink, have given rise to the prominent features of his landscape painting which is superior to his nature sketching. This shows that he comes nearer to tradition."
- Lang Shaojun
"With sharp, delicate intuition and mastery of subtlety between abstract and realistic images, Zhao Xiaohai's paintings show traces of experimentation that leads him to the borders of ink and brush works effects and emotions. I sincerely wish Zhao Xiaohai, after going through all the difficulties, will move ahead successfully."
- Yi Ying
"Prof Jia Youfu's influence on Zhao Xiaohai is obvious. Zhao's works highlight the depth and weighty power which are common of Jia's style. But he goes beyond that. While upholding Prof Jia's teachings and thoughts, he continues to learn from nature and ancient masters which help to develop his own charisma in art."
