On the afternoon of January 4, 2018, professor Cai Xiaomei, the " Chutian Scholar" appointed by our hospital, came to the hospital for the first time and gave a wonderful lecture to all the teachers in the hospital. Professor Cai explained vividly that the research comes from interest and needs curiosity and discovery in life and work with his own two research cases. At the same time, Professor Cai also said that research must be in dialogue with theory. Research without theoretical foundation is meaningless. Research must also go to the research object, plunge into and sink down, and carry out continuous research to form high-level research results. During the whole lecture, professor Cai's humorous way of explanation and vivid cases, especially the research closely combined with tourism, hotels and restaurants, stimulated the interest of all teachers in the study, greatly expanded the teachers' research ideas, changed the inherent cognitive model, and made the teachers truly feel the charm and fun of the study. From the evening of January 4 to noon of January 5, Professor Cai guided the three fund applications of 10 teachers one by one, put forward many valuable opinions and suggestions, and showed a high level of professional research. Professor Cai also held a discussion with all the teachers of the hotel department and gave guidance to the course setting and practice training of the hotel management specialty.
