After learning from Li Tong, Zhu Xi directed the Confucianism as the orientation in his life. From Li's reminding, Zhu Xi faced another vision, a "methodology of practice" dimension. Once, Li Tong required Zhu Xi to consider how to nourish "mind" and get rid of disturbance. In the aspect of philosophy of principle, Zhu Xi unfolded the practice of "keeping quiescence" and "keeping reverence." The former was to lead life enter quiescence by the way of adjusting breath and correcting mind. The latter was to fix the life on pure thought by the way of reminding the mind and focusing on one thought, and then the wild thoughts would be ignored. Zhu Xi carried the viewpoint of Neo-Confucianism in observing, writing, and even judging poems. In his opinion, before judging the poems fairly, people should keep the mind calm, and then the principle would unfold clearly. We must say that was Zhu Xi's subjective interpretation, but not necessary solving the question thoroughly. In addition, Zhu Xi used the imaginative poem language to describe the pure life with the metaphor of the flowing source. Zhu Xi drew an advanced practical state of life from the Neo-Confucianism and poetry description.
