Daguan Park is a lakeside park located in the southwestern suburb of Kunming, Yunnan, China. Today many locals come to sit, drink tea, fly kites, and go boating. Among shady walks and pools, Daguan's focal point is Daguan Ge, a square, three-storeyed pavilion built to better the Kangxi Emperor's enjoyment of the distant Western Hills and now a storehouse of calligraphy extolling the area's charms. The most famous poem here is a 118-character verse, carved into the gateposts by the Qing dynasty scholar Sun Ran, reputed to be the longest set of rhyming couplets in China. The park is set on Daguan Stream, which flows south into Lake Dian, and there are frequent hour-long cruises down the waterway, lined with willows, to points along Lake Dian's northern shore. Lake Dian, also known as the Kunming Lake, is the largest lake on the Yunnan-Guizhou Plateau. At Longmen of the Western Hills, there is a panoramic view of the lake.
