Wenlan Pavilion, Hangzhou, Zhejiang Province.

Wenlan Pavilion is one of the seven libraries that housed the Siku Quanshu (Complete Library of the Four Treasuries) during the Qing Dynasty, and the only remaining royal library in the Jiangnan region. The main building is a double-eaved, hard-roofed wooden structure modeled after the Tianyi Pavilion in Ningbo. It was designated a national key cultural relic protection unit in 2001. The site of Wenlan Pavilion was originally the Kangxi Palace, built in the 46th year of the Kangxi reign (1707). In the 5th year of the Yongzheng reign (1727), the palace was converted into Shengyin Temple. In the 49th year of the Qianlong reign (1784), Wenlan Pavilion was built in Shengyin Temple to house the Siku Quanshu. During the Xianfeng reign, the Taiping Army occupied Hangzhou, and Wenlan Pavilion was partially destroyed. In the 7th year of the Guangxu reign (1881), the library was rebuilt on the original site of Wenlan Pavilion. The existing building is a relic from the Guangxu period. In the first year of the Republic of China (1912), the Siku Quanshu housed in Wenlan Pavilion was moved to the Gushan Library (now the Ancient Books Department of Zhejiang Library) and taken over by Zhejiang Library. Since then, the pavilion and the books have been separated, and remain so to this day. To the left of Wenlan Pavilion is the Taiyi Fenqing Room, a place for scholars to copy, read, and rest. It was added when Wenlan Pavilion was rebuilt in the 7th year of the Guangxu reign (1881). Wenlan Pavilion was built on the site of the former Taiyi Palace, and the Taiyi Fenqing Room is located to the east (left) of Wenlan Pavilion. In terms of astronomy, "Taiyi Fenqing" means the east of the Taiyi star, hence the name "Taiyi Fenqing Room." The building was destroyed by fire in 1974, and the existing building was rebuilt in 2009. It is now open to the public as an exhibition of Qing Dynasty scholars' residences.
