The length of domestic training varies with the training content. Basic housekeeping training usually includes housework skills, household cleaning, cooking skills and communication skills, and usually takes 1 to 2 weeks to complete. Higher-level training in China, such as Yue Yue, nurses and senior housekeepers, may take longer, reaching 10 to 20 days, or even several months to several years. This is because these trainings need to involve more complex skills and knowledge, such as advanced cooking, advanced cleaning skills and customer service. In addition, the domestic experience of the trainees will also affect the training time. People with relevant work experience may master the training content faster because they already have certain skills and experience. In contrast, students without domestic experience may need to receive more comprehensive training for a relatively long time. Therefore, it is suggested to determine the appropriate training time according to the personal situation and the specific information provided by the training institution.
