What are the core fundamentals and components of Western Astrology?
西方占星术的核心基础与基本构件是什么？
Western Astrology is built upon four foundational pillars: the Planets (representing drives and psychological functions), the Zodiac Signs (representing styles of expression), the Houses (representing life domains), and Aspects (angular relationships between planets).
The Sun sign represents core identity and ego, the Moon sign reflects emotional inner life and instincts, and the Ascendant (Rising sign) governs outward persona and how one interacts with the world.
It relies heavily on tropical celestial geometry, measuring the sun's position relative to the vernal equinox to track seasonal archetypes.
西方占星术建立在四大核心支柱之上：行星（代表心理驱动力与内在功能）、星座（代表表现风格）、宫位（代表生活领域）以及相位（行星之间的几何夹角）。
其中，太阳星座代表核心自我与意志，月亮星座反映情感内心与潜意识本能，上升星座则掌管对外形象及与环境互动的方式。
西方占星依赖于回归黄道的天文几何学，以春分点为起点来界定四季的能量原型。
