“…The phenomenon of LBCs has drawn more attention in the literature. As a result, researchers have thoroughly examined how children's academic performance is affected by the "left behind" status brought on by parents' immigration, for example, (Chang et al, 2019;Bai et al, 2019;Chen et al, 2009;McKenzie and Rapoport, 2011;Xu, 2018;Zhang et al, 2014), educational outcomes (Wang et al, 2014), physical health (Murphy et al, 2016;Yu et al, 2014) and mental health (Chang et al 2019;Gao, 2010;Zhou et al, 2005).
