Located in the southeastern part of Henan Province, Huangchuan County has a warm climate and abundant rainfall. It is located in the northern part of the subtropical zone and is a suitable habitat for the northward movement of tropical flowers and trees and the temperate vegetation. "Gwangju" volume 28 records: "The genus of wood has laurel, a hibiscus flower, there are three kinds of red, white and yellow." From the northwest of the ruins of the ancient city of Huangguo, there is a hilly ridge that stretches for dozens of kilometers. Since ancient times, osmanthus has been planted on a large scale. Every time in the golden autumn, the sweet-scented osmanthus blooms and the fragrance floats, so it is named "Guihualing". The Huangchuan people have a custom of playing "Osmanthus cake", "Osmanthus sugar" and "Osmanthus wine" on the holidays.
