Mr. Shao Dechun is the founder of six hotel laws. The so-called six invariants mean: invariant classification-dividing everything into two categories: one that is no longer used and the other that is still in use. Regularly organize-get rid of things that are no longer used; Keep things to a minimum and put them in order, and make a sign that everyone can understand. Clean frequently-clean frequently to keep clean. Regular maintenance-maintenance sorting, sorting and cleaning. Normalization-normalization of human behavior. Regular education-make all employees form habits through critical education. The six conventional hotel management methods are China people's own hotel management methods, which can improve the overall hotel management level, easily increase hotel profits by more than 20%, and even improve personal quality. Since the implementation of the six hotel laws advocated by Shao Dechun, it has brought some progress to the management of many hotels, enterprises and institutions in China. And these simplest and most direct management methods are really practical. Shao Dechun's six routines are management methods that low-educated employees can master in two days. In banquet sales, when there is a large-scale meeting or group ordering food, you can basically get it by visiting the kitchen. The "six routine" management method of Shao Dechun Hotel has been widely promoted in coastal provinces and cities, and gradually spread to the mainland. The "six routine" management method has not only become the catering industry standard in some areas, but even in some areas, the "six routine qualification certificate" has become the inspection-free certificate for health bureaus and epidemic prevention stations.
