The southern quarter runs Well, Ghost, Willow, Star, Extended Net, Wings and Chariot, from Gemini through Cancer and Hydra into Corvus. It is the quarter that stands high in the evening sky in summer, and it carries summer, the phase Fire, the colour red and the direction south.
More than any of the other three, this quarter is read anatomically. The Willow is taken as the bird's beak, the Star as its neck, the Extended Net as its crop, and the Wings, which is a long spread of faint stars along Hydra's back, as the wings themselves; the Chariot closes the figure at the tail. The names of the individual lodges are older than the bird, and the bird is fitted to them rather than the other way round, which is worth noticing because it shows how the scheme was assembled: seven established asterisms are read as one animal so that the sky divides into four palaces of equal count.
Two of the lodges carried heavy omen traffic. The Ghost lodge contains a hazy patch, the cluster now called the Beehive, and its visibility or dimness was read for weather and for mortality. The Well lodge, at the boundary of the quarter, marks where the sun stands near the summer solstice, which put it at the centre of calendrical attention.
The vermilion bird is grammatically feminine in most English renderings by convention rather than by anything in the Chinese, which does not mark it, and the sources treat the figure as an emblem before they treat it as a creature at all.
