What books can change the old man's mind?

Poetry of Tang Dynasty and Song Dynasty is a book with poets Li Bai and Du Fu in Tang Dynasty and poets Su Shi and Xin Qiji in Song Dynasty as the research objects. Li Bai's poems and songs show his high-spirited attitude towards life and his unremitting pursuit of free will. Du Fu's poems are poetic expressions of Confucian spirit, expressing his sincere love for the country and the people. Su Shi has been relegated to another country for three times, and his ci shows the natural and unrestrained posture in the stormy life. Xin Qiji was an outstanding military poet in ancient China. His poems are full of patriotism and heroism. Old people can feel the spiritual realm of the ancients more deeply from Tang and Song poems. Leisure time, a cup of tea and three or five poems can not only preserve health but also nourish the heart.
