Hào means eyebrow; Quang means ray, light. At the eyebrows of the Buddha, there are white hairs that usually emit light around themselves (a halo). This is one of the 32 good marks of the Buddha.

Hào-quang: A Quick Summary of the Concept of the Buddha’s Halo:
The Buddha’s halo, also known as a halo, is a symbolic light surrounding the body of the Buddha in works of art. It represents the light of enlightenment, wisdom that transcends suffering, and pure spiritual energy. The halo is not a physical object but an expression of the sublime state of consciousness that the Buddha attained.
The Origin and History of the Halo Symbol Origin from Ancient Civilizations
The symbol of light surrounding deities is not unique to Buddhism. Ancient civilizations such as Egypt, Greece, and Rome all used the image of a halo to represent the sacredness of the gods. In ancient Egyptian art, gods were often depicted with a crescent moon or sun shining around their heads. As Buddhism developed, this symbol was adopted and transformed according to its own spirit. Unlike other religions that consider auras to be a divine gift, Buddhism emphasizes that this light is the result of spiritual practice, purification of the mind, and enlightenment.
