·    In this “cave” variant of pi, the stalactite / grapes can take the form of a short, slightly curved horizontal line (tips pointing upwards), with a “u” under it, making it resemble a tooth or (in this context) an eye. (In the hand variant of cha, the bold-T (“IK’”, symbolic of breath or wind) also can also look like this.)

Sub-variants (3)

·    A. Double “cave” with no grip/bracket.

·    B. Single “cave” with a grip having two struts infixed.

·    C. Double “cave” with a grip/bracket having two struts infixed.

Do not confuse the pi variants with grip with ch’u: in both cases, there’s a grip with infixed struts, ending in one or two elements each having a boulder outline. In pi the boulder outline is one or two “caves” (each with pond and optional stalactite/grapes), whereas in ch’u the boulder outline is one or two “LEMs” at the end of the grip/bracket.

·    Features: bird-head with hand-jaw.
