In G there are two hoea glyphs, rather similar yet with completely opposite meanings. Ga2-26 ('the fire generator') precedes the 1st period of spring when the sky roof is beginning to be pushed up, while Gb3-30 exhibits signs of its negative or opposite - beyond comes a dark season (the sky roof is lowered):

Ga2-23	Ga2-24	Ga2-25	Ga2-26	Ga2-27	Ga2-28
Ga2-29	Ga3-1	Ga3-2	Ga3-3	Ga3-4	Ga3-5

b3-25	Gb3-26	Gb3-27	Gb3-28	Gb3-29
Gb3-30	Gb4-1	Gb4-2	Gb4-3	Gb4-4

Gb3-30  is followed by a reversed hau tea (Gb4-1) and the location is Akahanga (where the sun king will be buried). The bottom part of Gb3-30 is not open at right like Ga2-26, the right limb is drawn down to the same level as at left. Furthermore, a little pau sign is added to tell that it (light from the sun) is 'finished' (pau).
