Introduction to Drinking: Historical records show that more than a dozen people, including Zheng Yu, Liu Shen, Guo Baoheng, Wang Chong, Zhang Daoyin and other scholars in Chang'an of the Tang Dynasty, were proud of the spring breeze, full of joy, relaxed and informal, and acted as if there was no one else around. Every spring, I take a bus to Qujiang for a spring outing, sit on a mat on grass, drink to my heart's content, take off my clothes and hats, laugh and shout, calling myself "drinking".
