1. Market demand: The market demand for home economics lecturers is relatively high. With the development of society, more and more families have an increasing demand for domestic service, especially for family education and child care. In contrast, the market demand of wedding hosts is relatively limited, and only in the wedding industry can there be a bigger market.

2. Service scope and time cost: Domestic lecturers have a wide range of services, including not only family education and parenting guidance, but also family management, cooking and other services. In contrast, the service scope of the wedding host is relatively narrow, limited to the hosting and organization of the wedding. The working hours of domestic lecturers are flexible and can be arranged according to the needs of customers. In contrast, the wedding host has to work according to the wedding schedule. The time cost of home economics lecturers is also relatively high, resulting in higher income.
