As for the name of the formation…
The formation initially had no name, and the initial creator was unknown. What had happened was a long time ago, there was a rather famous master by the name of Zhang Wu who painted eighteen lifelike sparrows that seemed to jump off the page. Not only that, each sparrow was painted following a different Dao that Zhang Wu had pursued in his life time, making it not only an invaluable piece of cultural heritage but also a cultivation treasure.
