Literature Reference: From 'Zi Xuan Cheng Fu Guan Shang Jing' by Du Mu: Ten years of carefree wandering in the rivers and lakes, every day with a wine cup lingering. By the stream at Xie Gong's city, dreams are startled; at Su Xiao's door, willows brush my head. Where in the thousand miles of cloud-covered mountains is the best place? The elegance of a few people ends in a lifetime. Hanging up the dusty official hat, knowing the leisure, I finally plan to wander and visit old friends.
