How to find your yongshin
Finding yongshin = pinpointing what the chart lacks and what it has in excess.
1. Judge day-master strength
Strong → suppressing god as candidate; weak → supporting god.
2. Climate check
Winter charts without fire freeze; summer charts without water dry. Climate may override 抑扶.
3. Conflict/illness diagnosis
Two strong opposing elements need a mediator. A specific "illness" character needs its "cure."
4. Pick the most reliable lever
Among candidates, the one actually present (or frequently incoming) is the real yongshin.
