"Terraced Fields in Yuanyang"
The Yi and Hani ethnic groups live on the mountainsides of the Ailao Range in Yuanyang County, Yunnan Province. Their terraced fields, cultivated for at least the past 1300 years (and pictured in historic bronzeware) stretch 2000 meters from the mountain top to the valley below. The Chinese government submitted this area as a potential UNESCO site in 2008 but it was not awarded world heritage status.
The sender of the card states that her hometown is Yunnan, but she currently studies in Beijing, and it was postmarked in Beijing. (I should be glad, because I received the card today; if she had sent it from Yuanyang, it would probably still be in the mail for another month.) I think the stamp says "Happy New Year."
