Lí below Xún: when the base of a person or situation is Lí, there is a clear order. Without that order there is no family, no coherence, just a group. Dedicated family members form a strong household, skilled musicians with their own distinct instrument form an orchestra, Daojia (“Dao family” or “school of the Dao”) is Daoism, the Templars are an 'order' of knighthood. Xún shows this order to the outside world as a coherent whole with a special base and spreads its influence.
