Guo Meimei, 20 - who goes by the name "Guo Meimei Baby" - may be just another young woman flaunting her wealth through photographs posted on Weibo, the Chinese version of Twitter, but her link to the Red Cross of China has sparked a national debate around how donations to charities are used.

The Red Cross of China is one of the country's largest charities and has strong ties to the communist government. And evidence of Ms Guo's extravagant lifestyle has made the Chinese suspicious in a country where the divide between rich and poor is growing and corruption is rife.

In her microblog, Ms Guo, whose name "Mei" means "pretty", has posted photos of herself with the sports cars, a pile of luxury Hermes handbags, sipping drinks in business class on a flight and showing off her luxury villa.
