Casting / Audition For TVC in China: No Idea what I’m Cast for…LOL

So my agent tells me to come to some location in Shanghai, China for a casting for a TVC (TV Commercial) and says it is something to do with a heater. Well, this is typically what happens when i go to a casting. Nobody really speaks good English so there is always some sort of misunderstanding. Anyway, i go to this casting and the next thing they want is my to take my cloths off and put a towel on..LOL. So instead of a heater, i am thinking a shower head? Right? Then they make me put some kind of goggles so maybe i am cashing for these goggles or maybe this TVC has something to do with swimming? Then i am suppose to pretend to grab something then point at the celling and i have no clue on what i am grabbing nor what i am pointing at in the sky. I am still trying to figure it out but i have learned to just keep cool and i will figure out what this casting was eventually about when and if the clients chooses me. So wish me luck! Thumbs up for luck! I will need it!
