In Malaysia, the man in the moon is an old hunchback sitting beneath an inverted banyan tree. He is plaiting bark into a fishing line to catch everything on earth. There is also a rat which gnaws through the fishing line and a cat which chases the rat. So long as this equilibrium continues, the world is safe, but if the hunchback ever completes his fishing line, the world will end. Wu Kang also cuts branches from the Cassia tree of immortality, which grows in the moon.
Bows obviously occur a lot in lunar myths, as crescent symbols.
Presumably because the willow grows near water, and readily regenerates when cut down or pruned. Willow is a source of Salicilic acid, the raw ingredient of aspirin, and was used in the past to cure rheumatic pain, which was supposed to be caused by witchcraft. Rejected lovers used to wear willow in their hats. Don't know why, but if the stump of a cabbage is left in the ground after harvest small cabbages will grow from it. Brussel sprouts grow in a neat clockwise helix, apparently following the path of the sun and moon, like vines.
