Kung Peng-cheng, president of Fokuang University, says that Zhu Xi was a multifaceted character, and a rather complex man. It would not be entirely accurate to say that he was a Confucianist, and in fact he wrote Taoist tracts under the assumed names Zou Ling and The Daoist from Kungtung Mountain. Taiwanese dialect works for him!
佛光大學校長龔鵬程表示，朱熹面貌多樣，其實是個滿複雜的人，若說他是儒家學者，他又不那麼門戶之見，他曾化名崆峒道士鄒訢，寫過多篇道教論著。
