The ticker tape translated, says:
Dear Chinese people, please eat pizza instead of torturing Tibetans.
This is wrong on so many levels, I don't know where to start. Yes, all chinese people living in Zurich are responsible for the situation in Tibet. Yes, it's funny and amusing to make jokes about a political and cultural situation you barely understood. And yes, this slogan will make them think twice and rush to buy overpriced, not very tasty, swiss pizza. I don't think so...
