"Dragon Raises its Head" is a folk festival based on observing changes in celestial phenomena. It has been regarded as a festival since ancient times to pray for good weather, to ward off evil spirits and to avoid disasters.

The formation of "February 2, the dragon raises its head" is influenced by the emerging festivals of the Mid-Tang Dynasty, the long-term accumulation of spring solar terms, and people's cultural tradition of making stacked numbers (even numbers) easy to recognize and remember.
