Bayinbuluke Prairie is composed of two grassland hills with a total area of about 23,000 square kilometers. It is China's second largest prairie, smaller only than the Ordos Grassland Prairie. The Mongolian word "Bayinbuluke" means "rich spring water." The famous "Swan Lake," China's one and only swan nature preserve is also in Bayinbuluke Prairie. [China.org.cn/Photo by Sun Jihu]
