Which of the following is correct about the relationship between folk culture and tourism?

Folk culture enriches tourism. Generally speaking, tourism includes six elements of tourists' food, shelter, transportation, shopping and entertainment, while folk culture covers six aspects of food, shelter, transportation, shopping and entertainment for ethnic residents in various regions. Therefore, it can be said that folk culture has greatly enriched the content of tourism. Second, folk culture deepens tourism. In other words, folk culture has increased the connotation of tourism. Folk customs involve the unique life culture of each region and nation. It has the characteristics of mass, heterogeneity and no political inclination, which conforms to the trend of tourism popularization and tourists' psychology of seeking differences. Fourthly, folk culture broadens the tourist targets. First, folk culture has increased the number of tourists, because there is no folk culture tourism, and it may just be tourism. Secondly, folk culture has increased the number of tourists, because folk tourism transcends national boundaries. According to the authoritative sampling survey in China, 26% of American tourists come to China mainly to enjoy the historical sites, while 56.7% of them are most interested in the lifestyle and customs of China people. In a word, folk culture can play a very good role in promoting tourism, which is proved by the great success of Shenzhen Folk Culture Village and the practice of Yunnan Folk Tourism developing into a major tourist province.
