 On one visit, long after the street protests were quelled, MPS John Ruich found that some yellow businesses remain, but a perfect storm is threatening them. In a shopping center in a bustling suburban part of Hong Kong, there's a tiny business called Nine Cake. They serve pretty little stacks of inch-thick pancakes covered in sweet sauces and whipped cream. How long have you been here in business? Four years. Angus Chan runs the place. The desserts all have names that play off of protest themes.
