Tai Yang (Sun Star) (太陽星), also known as the “Radiance Star,” belongs to the Bing Fire (Yang Fire) element with Yang polarity. Tai Yang is the 'Sun Star,' representing light, warmth, generosity, and altruism. Like the sun, it radiates outward to benefit others without expecting return. People with a prominent Tai Yang are naturally just, public-spirited, and eager to help the underdog. The Sun Star is stronger during 'daytime' positions (Yin-Mao-Chen-Si-Wu-Wei palaces) and weaker at 'night' (Shen-You-Xu-Hai-Zi-Chou), mirroring the sun's daily cycle.
