     The work of the hunchbacked shamans and lame-footed seers is to assess the yin and the yang, to divine the omens and portents, to drill the tortoise-shells and lay out the hexagrams, to preside over ceremonies for warding off ills, selecting lucky days, and the five prognostications, and to know good and bad fortune, the auspicious and the inauspicious.
