Lenglongling is located in the northeast of Menyuan County. It has a glacier on the top and is covered with snow all year round. Whenever the sun sets in the west, the sunset glows lightly, and the crystal white snow on the top of the mountain shines brightly, sometimes in bright red and lavender, with light shades of dark blue. Like a jade dragon flying among the flowers, it changes constantly, so it is called the cold dragon in the sunset.
