Domestic service is no longer regarded as a vulgar job, but an industry under social division of labor, just like all other occupations. In 2000, the Ministry of Labor and Social Security officially recognized the profession of "domestic servant", and domestic service embarked on its own "professional" development path. The Ministry of Labor and Social Security put forward that domestic service should be developed as a new field to expand employment, and domestic service should be regarded as a formal occupation of the country. Domestic service is a cross-century "win-win" project. On the one hand, it provides a full range of service systems such as nanny, nursing, cleaning, family education, logistics and distribution, and family management. On the other hand, it is one of the main channels to solve the re-employment problem. According to the survey of Labor and Social Security Bureau, domestic service has great employment potential, which can provide at least 5 million jobs for China. Modern domestic service is no longer a simple nanny and servant in the traditional sense, but a complex, comprehensive and high-level service, so the training of domestic servants has become the basic requirement of domestic service and the only way for domestic servants to improve their service quality and skills. ?
