This is a place for emperors to study and cultivate themselves, as well as to enjoy entertainment. The emperor often hunted here, practiced martial arts, held grand banquets, escaped from the troubles of politics, and felt happy in an environment of desirelessness and humility. The variously shaped pavilions and ponds blend with nature, making it impossible to distinguish what is architecture and what is nature. Especially in the season of deep autumn dyed by maple leaves, or in the time of falling leaves, the beauty here always stirs up a kind of "ambition" to monopolize it.
