Why is the Day Master Your True Self?

While the public is familiar with the 12 Chinese Zodiac animals (based on the birth year), professional astrologers focus primarily on the Day Master. The Day Master reflects your true character and internal reactions to environments, whereas the year animal represents your social circle and grandparent roots.

There are 10 unique Day Masters in BaZi, formed by combining the 5 Elements (Wood, Fire, Earth, Metal, Water) with Yin and Yang polarities. For example, a Jia Wood Day Master represents a tall, sturdy redwood tree, showing leadership and ambition, while a Yi Wood Day Master is like a flexible creeping vine, representing diplomat skills and rapid adaptability.
