On the northeast corner of Diān Chí, the Yunnan Nationalities Museum (云南民族博物馆, Yúnnán Mínzú Bówùguǎn) is reputedly the largest museum focused on minority cultures in China, boasting two floors of exhibits on traditional costumes, masks, folk instruments, pottery, folk-patterned roof tiles and eaves caps of many Chinese minority groups. It's a 1 km walk south of Line 5’s Yuhu Cun station. The museum is closed on Mondays.
Don't confuse it with the theme-park-like Yunnan Nationalities Village across the street, a large park with reconstructions of "traditional" villages of 26 of Yunnan's minority groups, which some visitors will find objectionable on account of elephant performances and the general theme-park atmosphere.
