Google Translate might not be very clear, but the article actually says that Li Ka-Shing denied authorship of this article on 20 February 2013. (Yes, 2013!)

This current resurgence is probably linked to an English translation being posted on e27 in the past 24 hours, before being subsequently picked up by TRS: http://mirror.e27.co/li-ka-shing-teaches-buy-car-house-5-yea...

Just a note that The Real Singapore is not representative of Singapore's media scene.. while it is not quite an equivalent of The Onion, it is also not the first news source for most locals. I am quite embarrassed to see it linked to on HN.

Google Translate: "Li Ka-shing, said through a spokesman, He never made similar remarks."
