I am Sun Kun, a professor in the School of Tourism & Culinary, Yangzhou University. I got a master degree in the major of tourism geography, and a doctor degree in the major of tourism resources. Additionally, I had a postdoctoral experience in the major of ecotourism. I have been a teacher for 22 years, and the lecture courses include ecotourism, tourism plan and development, tourism destination management, tourism culture, tourism enterprise management, tourism behavior, and so on. Besides these, I had ever been a volunteer teacher in a middle school in the Tibetan Plateau, and ever served a temporary position in a travel bureau of a county in Jiangsu Province. In the teaching and social working, I acquired the knowledge and understanding on tourism sustainable development. I am very interested in researches on ecotourism destination operation, management and marketing. In these years, my researches focus on ecotourism of national parks that are being established in China, ice–snow tourism destinations that are attracting lots of attention after the Beijing 2022 Winter Olympics, and original and ecological food in ecotourism regions. In the above areas, I have carried out 7 research programs funded by the national or prefectural science foundations; and commissioned by some regional authorities, I have presided over 12 scientific research projects about regional tourism development, among them three being relevant with ice–snow tourism and two being relevant with ecotourism
