With the development of information exchange and transportation, and the huge flow of people from all over the country, the regional taste differentiation is not obvious, unless there are some remote places or places where few people go, so as long as the prepared delicious food is generally acceptable to the people, but it is related to the acceptance rate and return rate, you should do a survey yourself, that is, do a free tasting activity or give it to your relatives and friends (the latter method is not recommended, you know), and then do it.
