Mountain 11 of the twenty-four mountains (luopan) is Xun, one of only four trigrams placed on the ring, occupying position SE2, due southeast, 127.5 to 142.5 degrees. Xun is the Gentle, Wind and Wood, the Eldest Daughter in the family of trigrams set out in the Shuogua, the Discussion of the Trigrams, and it belongs to the phase Wood; its associated animal is the fowl or hen and its body part the thighs. Doubled upon itself Xun forms hexagram 57, The Gentle, whose reading counsels that lasting effect comes from mild but ceaseless action, like wind that shapes the dunes or a root that splits rock.
Of the eight trigrams of the Bagua, only the four occupying the diagonal, ordinal directions, Qian, Kun, Gen and Xun, appear as named mountains on the twenty-four position ring; the four cardinal trigrams, Kan, Li, Zhen and Dui, are not separately inscribed because their own Later Heaven positions, north, south, east and west, coincide with the ring's four pure cardinal branches instead. In the Earlier Heaven (Fuxi) sequence, a second traditional arrangement of the same eight trigrams recorded separately in this atlas, Xun occupies the southwest, opposite its Later Heaven position of the southeast, a reminder that the twenty-four mountain ring follows only the Later Heaven scheme and not the Fuxi one.
