Dig a pit in the ground one chi (approx. 30cm) deep, line the bottom with tiles, place four liang (approx. 120g) of prepared Ai Ye (Artemisiae Argyi Folium) on the tiles, and ignite it.

The voice then transmitted this formula and disappeared. Cui took it, and within months, his eyesight was restored. Thus, it was passed down.
