Chen is the fifth Earthly Branch, belonging to Yang Earth, associated with the Dragon zodiac sign, and corresponds to the Chen Hour (07:00–09:00). Chen Earth represents moist earth of late spring, internally concealing Yi Wood, Wu Earth, and Gui Water; its nature is damp and inclusive, symbolizing transformation, accumulation, and embracing capacity. Chen Earth functions as a 'water reservoir', embodying the imagery of storage and moistening.
Chen Earth is identified from the Earthly Branches of the Four Pillars in a Bazi chart. If Chen appears in the Year Branch, the native belongs to the Dragon zodiac; if Chen appears in the Day Branch, the Spouse Palace is Chen Earth. Chen Earth is strongest during Chen Month (the third lunar month).
A person born on a Jia-Chen Day has Chen Earth in the Day Branch acting as Indirect Wealth; their spouse excels at financial management, and the family enjoys substantial material resources.
