Yushu Tao Te Ching

Dragons can be big or small, they can rise and disappear; when they are big, they stir up clouds and spit out mist; when they are small, they hide and hide their form; when they rise, they soar in the universe, and when they are hidden, they lurk within the waves; the way of dragons is also the way of kings; there are real dragons in the world, with supreme merits, who can be the saints and emperors of the world; there are also hidden dragons, calm and indifferent, not visible to the world.
