wu ray-kuo. we will continue our conversation with dr. yu-chien chang, the assistant professor of management. we talked a lot about the different strategies we can use to promote a different city or country. how about some other strategies you can recommend? any interest in trying to promote tourism, having more visitors coming to your city, trying to show the local festivals and trying to get them identified with the local values that are so attractive to some of them very lax in terms of the marketing strategy, in the beginning, i usually like to ask who is your audience, who is your visitor, and this relates to the positioning questions. you position yourself and the local market or international market. before we really start, we can think about these kinds of questions. the most important part, not only in cultural estoppels, but commercial activities. we have to think about it it's not the only time. if we have the festival happening every year or regularly, how can we attract visitors to come back again? this is another issue we have to think about. innovation would be very important.
