In fact, if you read Kangxi's question carefully, you should find that when they introduced the food, they already said the place of sale. Because I am very familiar with the detailed place names of every region in Taiwan Province Province, I can't give you an answer for sure. However, if you come from Taiwan Province Province or are familiar with Taiwan Province Province, you might as well go and see for yourself. After all, the food is really delicious, and there is little or no food in mainland China, so you can only go there to taste it yourself.

Because programs in Taiwan Province Province or public-oriented video programs (such as TV dramas and movies) generally avoid naming food or place names directly to avoid advertising suspicion, they are generally not accurate. If you are in Taiwan Province Province or are familiar with it, you can take some words or food names mentioned in the program as clues, go to a nearby store or ask people nearby. Or if you can find friends who grew up in Taiwan Province province, that's the best. I think nine times out of ten they know the "home" of the food they introduced after watching that program.

I'm sorry I can't give you the exact answer you want, but I hope my answer can help you.
