Wang Zhaojun’s Tomb, also called “Green Tomb”, is the place where Wang Zhaojun (a princess in the Han Dynasty of ancient China) was buried as according to people’s legend. It is located at the south bank of DaHei River, the southern suburbs of Hohhot. It’s said that it was built in the West Han Dynasty of ancient China about 2000 years ago, and it was rebuilt in the 1970s, with a 33-meter height, covering 13,000 square meters. It is one of the largest Han tombs and among the key cultural and historical sites in China.

Wang Zhaojun’s original name was Wang Qiang. She was  known as one of the Four Beauties of ancient China. Born in Baoping Village, Zigui County (in current Hubei Province) in the Western Han Dynasty (206 BC–8 AD), she was sent by Emperor Yuan to marry the Xiongnu’s Huhanye Chanyu  in order to establish friendly relations with the Han Dynasty through marriage.

In the most prevalent version of the "Four Beauties" legend, it is said that Wang Zhaojun left her hometown on horseback on a bright autumn morning and began a journey northward. Along the way, the horse neighed, making Zhaojun extremely sad and unable to control her emotions. As she sat on the saddle, she began to play sorrowful melodies on a stringed instrument. A flock of geese flying southward heard the music, saw the beautiful young woman riding the horse, immediately forgot to flap their wings, and fell to the ground. From then on, Zhaojun acquired the nickname "fells geese" or "drops birds."
