Relationship compatibility, synastry and 合婚 in one reading
A compatibility reading overlays two people's charts to show how they fit, where they clash, and what draws them together. Tian Qi reads it two ways at once: Western synastry, which lays one partner's planets over the other's houses and measures the aspects between them, and Chinese 合婚 (hehun), which compares the two 八字 (BaZi) charts and 紫微斗數 (Zi Wei Dou Shu) charts for elemental harmony and clash. Together they give a fuller picture than either tradition alone.
How Tian Qi reads a compatibility chart
Enter both birth details and the calculator builds a two-skies (bi-wheel) chart, scores the harmony, tension, and attraction between the two, and surfaces the specific synastry aspects and 合婚 relationships that drive them. The AI then reads the overlay in plain English, naming where the connection flows and where it needs work, tied to the actual placements rather than sun-sign clichés.
