Earth feeds Metal
Earth feeds Metal in the five-element cycle, so 己 tends to give and 庚 tends to receive. 己 often brings support and ideas, and 庚 brings warmth and results. Making sure the giving goes both ways keeps it balanced.
One yang stem and one yin stem: one tends to push forward and the other tends to read the room, which often fits well.

If you are one of them
If you are Yin Earth and your partner is Yang Metal
With your core element, earth, meeting your partner's metal, you are the nurturing one in this flow. Saju's generating cycle (相生) says earth produces metal, so your steadiness helps your partner feel secure enough to be ambitious or precise. You may be the calm voice that talks them down after a stressful day. They may help you set boundaries you would never set alone. Picture a quiet mountain that holds a bright, clear spring of minerals. Protect your energy by keeping one space in your week that is only yours. When the mountain rests, it has even more to give.
If you are Yang Metal and your partner is Yin Earth
Here, your core element, metal, is nourished by your partner's earth. Saju calls this the generating cycle (相生), where earth helps metal form and strengthen. In practice, your partner may give you stability, practical help and patience that let you focus on your goals. You might be the sharp strategist and they the reliable foundation. Picture a jewel set into a solid ring. The setting matters as much as the stone, so honor your partner's contribution openly, both at home and in front of others. When earth feels seen, it keeps offering the steady support that helps you shine.
