Originally built in the reign of Emperor Qianlong, this hall is shaped as if it were a folding fan. The ribs of the fan are the steps in front of the hall, which are made from stone slates; its axis is white marble. Hence the folk name “Hall of the Fan Blade”. Its official name “Wind of Virtue” comes from a story in the Biography of Yuan Hong, Book of the Jin Dynasty. When Yuan Hong was leaving to take up his new post as governor of Dongyang, Xie An, Prime Minister at the time, presented him with a fan. Upon accepting the gift, Yuan replied: “I will fan the wind of virtue to comfort the common people”, indicating that he would make good policies to appease the common people.
