Monday marks the 28th day of the 12th lunar month.

According to Chinese tradition, it is a day designated for "spring cleaning", when families deep-clean their homes in the run up to the Lunar New Year and put up new "fai chuns" -- red banners bearing auspicious phrases.

While the market is flooded with mass produced, digitally-printed "fai chuns", many people still prefer the more traditional, handwritten ones that are becoming quite rare these days.
