Engagement is a ceremony held before marriage to prove the relationship between the two sides, indicating that the relationship between the two sides is moving towards a wedding. It can also be understood as an agreement to prove the relationship between the two parties, which is not protected by law. It means giving each other the happiness of the rest of my life. The elders of both men and women agreed to get engaged. Although it is an era of free love, they still need to seek the opinions and suggestions of their parents and elders in the face of such a lifelong event as marriage. So they need to communicate with their parents and elders about their engagement before they get engaged. Especially in a family with a relatively traditional concept, or a big family, engagement is a big event for the whole family and must be discussed with the elders.

Staffing refers to the establishment of various institutions in state organs, enterprises, institutions, social organizations and other work units, and the allocation of the number of personnel, structure and positions. National staffing is mainly divided into administrative staffing, institutional staffing, enterprise staffing, etc. In the era of planned economy, the employees in enterprises are similar to those in state administrative organs and institutions, that is, the personnel officially established by the state (personnel department). The basic salary and local subsidies are financial allocations, and they must be openly recruited before they can enter the establishment. Non-staffing personnel are employed by institutions themselves (including temporary workers), and there is no financial allocation, just like enterprise employment.
