A full-page advertisement in a major Guangzhou newspaper imitating a woman gloating over an extramarital affair, but which is actually part of a cosmetic brand's campaign, stirred up heated debate and was canceled, with claims it is a challenge to social morality.

The advertisement, which looks like a letter, was printed on Tuesday in Southern Metropolis Daily, a major newspaper in the capital of Guangdong province.

The fictitious writer, who refers to herself as Mrs Zhang, asks Zhang's ex-wife to let him go and gives her advice on how to find her own Mr Right.
