For the purposes of this question, a focus means something needed to cast a spell properly, something that channels magic, or something that allows magic to be cast. (This could include a magically enchanted item)
In most Myths and Legends that I'm aware of, the caster normally uses a wand or a staff to create magic (scepters are also popular). I'm not well versed in Chinese Mythology, and so I am wondering whether there are objects that are used in a similar manner in their Mythology.
What objects allowed the users to cast/channel/focus magic either from the user or from the object in Chinese Mythology?
I may even consider a grimoire or tome like object if just for sake of completeness
