Abstract: With the advent of the era of negative population growth in China, the problem of population aging is becoming more and more prominent. In order to actively respond to the problem of population aging, the policy of postponing the legal retirement age is gradually implemented on January 1st, 2025. On the one hand, the postponing retirement policy helps to improve the utilization rate of the labor force and population resources of the whole society. On the other hand, the postponing retirement may also affect the generation of society and families. The postponing retirement requires appropriate adjustment of the internal division of labor within the family, but this adjustment may lead to short-term inconvenience to family life. In addition, the postponing retirement may lead to a longer job retirement cycle in the system, which is not conducive to the stable employment of the young labor force.To this end, the relevant state departments should take countermeasures in many aspects such as the infant care support system, the allocation of regional education resources, the coordinated development of the intergenerational employment market, and the improvement of relevant laws and regulations.

Key words: postponing retirement, intergenerational support, family function
