In preparation for the post-coronavirus era, overseas exchanges are being revived. As a result, the potential desire to travel overseas will suddenly explode, and an increase in the number of tourists is expected in all regions. However, congestion at famous tourist destinations can lead to lower tourist satisfaction and missed opportunities from an economic perspective. The aim of our research is to guide people to nearby attractive tourist sites as a way of avoiding crowding at tourist sites. Specifically, from an economic perspective, the method is proposed to comprehensively evaluate alternative sites as candidates for the tourist sites one originally wants to visit, based on the similarity of tourist resources, interest, popularity and travel distance.
