This study demonstrated that the size of social networks has a positive effect on SWB. Social networks refer to relatively stable relationships between individuals within a certain range (McLaughlin et al., 2010). The so-called individual’s perceived social support network means social networks, whereby individuals can obtain a variety of resources for support (such as money, emotions, friendship, etc.). Through the help of perceived social support, and through the help of support network, people can solve their daily problems and crises and maintain the normal operation of everyday life. Good perceived social support network is considered to help relieve the pressure of life and promote the health of body and mind (Symister, 2011)
