you do directly to the parent who is capable, and ask clear help

I ran a calligraph table for an international culture event as I was asked to. 

Anyone can ran this table, just write a few sample chinese characters, provide the fur brush and paper. Most of people won't jump out as they have never done something like this before. So just ask directly, and make yourself clean on what you wanted. Don't just complain and wait for people to jump out.
