Protagonist goes in search of distant relatives in China.

There is a scene in which a family is sitting around a table and the patriarch is about to give a toast.  He barely gets five words out before the matriarch yells “Bonsai!” and does a shot.  He continues on with his toast until a few seconds later, “Bonsai!”  Grandma does another shot.  This goes on three or four times before Grandpa finally grabs the bottle from her and finishes his toast in a very hurried voice, then yells “bonsai” himself before drinking his shot.
