Water points lie

inside the elbow (Lu5, Pe3, H3) and in the knee area (LV8, Sp9, K10) or
on the outside of the finger base joints (SI2, TW2, LI2) and on the toe joints (B66, G43, St44).
They eliminate cold and wetness (e.g., cold legs, especially Lu5 and LV8, Sp9, K10).

Metal points lie

inside above the wrist (Lu8, Pe5, H4) and in the ankle area (LV4, Sp5, K7) or
on the outside of the fingertips (SI1, TW1, LI1) and on the tips of the toes (B67, G44, St45).
They are only important in connection with the mother-son relationship.

Earth points lie

inside the wrist (Lu9, Pe7, H7) and in the middle foot area (Le3, MP3, N3) or
outside at the elbow (SI8, TW10, LI11) and knee area (B40, G34, St36).
They expel mucus and wetness (for example, heavy legs, especially Pe7 (heart), Lu9 (lung), Sp3 and LV3 drain moisture).

Fire points lie

in the middle of the hand (Lu10, Pe8, H8) and in the toe area (LV2, Sp2, K2) or
outside on forearm (SI5, TW6, LI5) and lower leg (B60, G38, St41).
They expel heat or fire (e.g., great agitation, H8 summer heat, Pe8 heart fire, Lu10 lung heat, LV2 liver fire, Sp2 fever, K2 void heat).

Wood points lie

inside at the fingertips (Lu11, Pe9, H9) and next to the toenails (Le1, MP1, N1) or
outside behind the metacarpophalangeal joints (SI3, TW3, LI3) and on the instep (B65, G41, St43).
They expel internal wind (e.g., acute headaches, neck complaints, especially SI3, K1, Sp1, LV1).

Example: The element point LI1 is a metal point.
The mother point is LI11, a earth point. As a mother point, he tonifies the son, LI1, and thus strengthens the Large Intestine function.
(Example: A typical metal problem (dryness) is sluggish digestion, and the nut (moisture) element aids digestion.
Mental: sadness, depression of a metal complaint is resolved by realism and reason of the earth element.)

The son point is the point LI2 following LI1. As a sons point, he sedates (calms) LI1, and thus the colon function
(Example: A cramping such as intestinal colic is “cooled”, ie dissolved by the water element (reassurance).)
