I'm pretty sure that image is a joke. However, are you asking about the custom of Chinese pinatas? I remember reading that the Chinese were actually
the ones who invented the pinata and not the Spanish but that's all I really know. If Chinese pinatas are what you are asking about, I can do some
Google searches for you but the image is meant to be humorous, most likely with a political angle.
To respond to your edit: Yes, I'm pretty sure that is Mao, which led me to believe the photo was political humor. Can't tell who is on the inside.
It's hard for me to see. It doesn't look like Lenin to me, though. His facial structure was more bony but the man inside the statue has more filled
out facial features. I could be wrong but the outer looks like Mao but the inside is not Lenin.
Thanks Ash!
It's just been on my mind if this were not a joke, but a real ceremony. Japanese and Chinese customs are not well known to me.
BTW, I don't think the funny caption is original to the photo,The writing with the pic are from punditkitchen.com.
It does seem to be a type of political humor. Based on the goofiness of it, I wouldn't be a bit surprised if it turned out to be a still frame from a
Japanese game show. Though the photoshop angle could be a correct assumption. I dunno, my vote is a game show of some type.
This is obviously a photoshopped image. You can see the shadow of the man (woman?) with the hammer making it seem as if s/he is very close to the
wall. The shadow of the piñata (as well as it's size) make it appear that it is behind the hammerer. If this were the case, the person with the
hammer would be ahead of the piñata, and it would make no sense. All this, of course, assumes that the shadows are even real. The statue inside
(which I think is Lenin, the joke would make sense, then) if imagined in full (or even as a bust) does not appear big enough to fit inside the
head.
