Wenshan (Chinese: 文山市; pinyin: Wénshān Shì; Zhuang: Vwnzsanh Si), old name Kaihua, is a city in and the seat of Wenshan Zhuang and Miao Autonomous Prefecture, in the southeast of Yunnan province, People's Republic of China.

[1] The Wenshan Zinc Mine is known for producing world class, deep blue hemimorphite specimens.

[3] Wenshan is a producer of 'Sanchi', a plant with medicinal properties which grows away from daylight under huge plastic sheets.

Due to its low latitude tempered by its high elevation, Wenshan has a mild humid subtropical climate (Köppen Cwa) with short, mild, dry winters and warm, rainy summers.

Because it is on a plateau, temperatures are quite constant throughout the year, with more precipitations during the summer months.
