Previously it was mentioned that Nan Zhubin had already become a part of Li Minglu's [social support system].
The [social support system] refers to the various forms of assistance, resources, and support an individual can obtain from their social network, having a significant impact on their mental health, life satisfaction, and stress coping ability.
Generally speaking, a person's social support system includes "social welfare" and "community services," which are formal supports provided by the government or society, and "family," "friends," and "colleagues," which are informal supports formed by personal social networks.
The more complete and complex the social support system, the more diverse and profound help it can provide to an individual.
This is also the origin of that classic psychology joke — my friends suggest I see a psychologist, while the psychologist suggests I talk more with my friends.
