One thing surprises me in china, while nudity is not allowed on TV at all, adds in general, for whatever product, ARE EACH PASSING DAY A LOT RISKIER, like the only way to attract your eyes is with a very provotative and sexy posed photo or drawing. 

The one that I recall that made me pay more attention was of a dentist, showing a patient on a dental chair and he working on a tooth.  The photo included a nurse or assistant, leaning over, and showing more cleveage than you will normally see.    Well, Hugh Hefner will be happy about this. 

Of course they are, and they will always continue to push the envelope and get away with what they can.
Sex sells, no matter where in the world you are.

I've never seen anything like that before. Usually if they know there product is not selling that well they like to add something that doesn't even represent their product. There are many commercials and ads nowadays that have these sorts of ways to attract peoples attention. I think there was a statistic somewhere that showed this trend. The people that added like you saw a naked person had better sales later on and that's the only reason they do it. Again it could be because the product they are trying to sell hasn't been selling well in the past. 

Hey you remembered the socks, so the add worked.

Score one more over overly sexed adds.

An advert I saw in a bar had a picture of a seated naked woman with the beer covering her (ahem) modesty. I was concerned this would make the beer warm.
