Recent tourism statistics shows that out of 2 million Chinese inbound tourists, 8..7% prefer Jeju to Hawaii or Maladive as a tourist destination. Based on a thick description on Chinese people`s behavior characteristics, this study suggests some administrative measures for Jeju tourism development. From a theoretical point of view, this study relies on institutionalism which focuses on the role of government and market economy in tourism development. Reviews of related literature on Chinese people`s cultural characteristics yields four key words of Chinese people`s behavior characteristics: social tie, true friendship, leisurely conversation, good foods with good people. Based on the findings of these ethnographic characteristics of Chinese people, as a administrative measure for Jeju tourism development, this study suggests to enclose fortified confucianism with the concept of true friendship for counter-studying abroad. It also proposes to develop a cultural tourism space where Chinese people could appreciate slow life style and leisurely conversation with good food in the midst of world-wide well-known natural scenery and snow of Jeju. Finally, this study suggests to develop a luxury water-bar furnished with pure water produced in Jeju Island for medical tourism.
