In general speaking, although Mao Chi-Ling's Study of Shan Shu doesn't get positive reviews in the academia, it does have some reference values. For example, we could find that Mao Chi-Ling criticized intellectuals of Song dynasty in his writings of Study of Shan Shu. In the meantime, he pointed out that intellectuals of Song dynasty who did not have the correct method of researching. He provided a new viewpoint, and has established his own as a special position in the academia in Qing dynasty. As reading writings of Mao Chi-Ling's Study of Shan Shu, we could find that all citations were from the writings wrrtien by intellectuals of Han dynasty, when Mao Chi-Ling wrote He Tu Luo Shu Yuan Chuan Bian, Guwen Shang Shu Yuanci, Shan Shu Guangtinglu and Recovering the Lost Shundian. This research method was the same as the Evidential scholarship during the Ch’ien-Chia Eras. it's the reason why intellectuals of Qing dynasty still identified with Mao Chi-Ling.
Research on Qing dynast Shan Shu studies has focused on the problem of determining the authenticity of the New and Old Text versions of the work. That's the reason why the evaluation of Shan Shu Guwen Shujheng which is written by Yan Ruo-Qu is better than Guwen Shang Shu Yuanci which is written by Mao Chi-Lin. In this article, ther is more deeply analysis and discussion about this issue.
