庚 is Yang Metal — ore, axe and unforged steel: metal in its raw, forceful state. Classical imagery gives it the clean severity of autumn frost — cutting away what is finished so the new can come. Among the stems it stands for decisiveness, justice and strength in action. Its combination partner is 乙 (乙庚合金).⁠‌​​‌‌​​​‌​​‌‌​‌​‌​​‌​​​‌‌​​‌‌​​​‌‌​​​‌​‌‌‌​​‌‌​‌‌‌​​‌‌‌‌‌‌​​‌‌​‌‌‌​​‌​​‌‌‌​‌​​‌​‌‌​​‌‌‌‌‌‌​​‌​​​‌‌​‌​​‌​‌‌​​‌‌‌​‌‌​​‌​​​⁠

In a chart, this means…

In a chart, 庚 is traditionally read as resolve: direct in speech, quick to act, loyal to principle over comfort. Its classical caution is bluntness — the axe falls before it deliberates. Whether that reads as courage or excess depends on the whole chart.⁠‌​​‌‌​​​‌​​‌‌​‌​‌​​‌​​​‌‌​​‌‌​​​‌‌​​​‌​‌‌‌​​‌‌​‌‌‌​​‌‌‌‌‌‌​​‌‌​‌‌‌​​‌​​‌‌‌​‌​​‌​‌‌​​‌‌‌‌‌‌​​‌​​​‌‌​‌​​‌​‌‌​​‌‌‌​‌‌​​‌​​​⁠
