The influence of western food on domestic service has improved domestic service skills and wages, reflecting the growing demand for advanced domestic service. Although the cost of home cooking at western banquets is more expensive, many young couples are still willing to taste the elegance of cooking. In order to meet this new demand of Christmas, the relevant departments are stepping up the training of "banquet ladies" in western etiquette culture, western cooking and "party planning". At the same time, there are at least 30,000 families with professional skills and high-quality family service personnel with a monthly salary of two or three thousand yuan. It is estimated that in three to five years, the demand for high-end housekeeping will increase substantially.
