在本书编写过程中，参考了国内外同行的相关著作，并得到了上海东方佘山索菲特大酒店、安徽工商职业学院、玉林师范学院、山东城市服务技术学院、广东环境保护职业技术学院和中国轻工业出版社的大力支持，在此一并表示感谢。 由于笔者的水平有限，行业发展速度快，知识更新等原因，本书难免在体系、观点及论述过程中存在不足，期盼同仁及广大读者批评指正。(The book has gratefully consulted works by Chinese and foreign colleagues and received support from Sofitel Shanghai Sheshan Oriental Hotel, Anhui Business Vocational College, Yulin Normal University, Shandong City Service Technician College, Guangdong Polytechnic of Environmental Protection Technology and China Light Industry Press. Due to the author's own limitations, the rapid evolution of the industry and upgrade of expertise, some errors in terms of structure, viewpoint and exposition are inevitable. We look forward to hearing suggestions and corrections from colleagues and readers.)
