A poster from Shek Kip Mei post office. Here are the popular Hong Kong cartoon characters McDull and McMug encouraging us to keep our letters tidy if we want them to be delivered. Alice noticed the red rabbit and black pig stamps that were used in kindergartens to let kids know if their work was tidy or not. She wonders if they are still used now. She also tells me that the black pig has made its way into Cantonese - if you don't keep your room tidy, you might just 'get a black piggie'.
