The fu, or Chinese axe, was originally used, as most axes are, for chopping wood. Even though it later became a weapon, it was a rare sight on the battlefield because of how incredibly heavy it was.
Some axes were beautifully carved and kept as art.
To fight Erlang Shen in Splitting the Mountain, the son of a goddess uses a magical axe given to him by a Taoist master to split the mountain and rescue his trapped mother.
