The story about the marriage of sister and brother Nüwa and Fu Xi told how they invented proper marriage procedures after marrying. At that time the world was unpopulated, so the siblings wanted to get married but, at the same time, they felt ashamed. So they went up to Kunlun Mountains and prayed to the heavens. They asked for permission for their marriage and said, if you allow us to marry, please make the mist surround us. The heavens gave permission to the couple, and promptly the peak was covered in mist. It is said that in order to hide her shyness, Nüwa covered her blushing face with a fan. Nowadays in some villages in China, the brides still follow the custom and use a fan to shield their faces.
