Mulanyu is located in Dazhouzhuang Village, Yingkuo Town, 35 kilometers south of the county seat of Shangqiu City, Henan Province. It was built in the Tang Dynasty 1300 years ago. The sand field sleeps with a knife and gun at night, and the flowers are yellow in a few dreams. Waking up to find Yujaor, it is a long-edged condensation frost.
