I took this picture today at a supermarket. The first thing that came up in my mind was "Why is this called 沙士?" and it took only seconds for me to remember the reason. This soft drink has brought back some childhood memory.
No when I was little we didn't have soft drinks imported from Australia. But we had a root beer by Watson's called Sarsae, which is still available today. Its Chinese name is 沙示, which I think has to do with the ingredient Sarsaparilla. In Taiwan a similar drink is called 沙士. The wiki has more information. So this is why root beer is called 沙士/示.
Whenever I think of the Sarsae drink I remember the song George Lam (林子祥) sang for its ad. It was a cover version of
, and in place of "sunny" he sang "沙示". I can still sing the song today. Too bad I can't find that commercial online.
