Why it is blocked: He is the son of current Chinese Premier Wen Jiabao. As reported in the Financial Times, Wen’s name was blocked on search engines back in 2010 when his equity fund neared $1 billion in capital: "[The government and the younger Mr Wen] definitely don’t want anyone in China to know that the premier’s son is doing a big investment fund," one person familiar with New Horizon said.
