Probably most people I know are familiar with the sugar syrup version we have in singapore. But in Hong Kong, they eat in the yolo way, the tau huey is given to you without any sugar or syrup. On the table, they provide your own desires, orange sugar, ginger syrup or sugar syrup, all up to your decision. Some people refill the sugar every few mouthfuls some prefer it pure. I prefer the orange sugar the most but in a tame way.
