(i) In dynamical dark energy models, compared to $\\Lambda$CDM, the upper limit of $\\sum m_\\nu$ can become larger and can also become smaller. In the cases of phantom and early phantom (i.e., the quintom evolving from $w<-1$ to $w>-1$), the constraint on $\\sum m_\\nu$ becomes looser; but in the cases of quintessence and early quintessence (i.e., the quintom evolving from $w>-1$ to $w<-1$), the constraint on $\\sum m_\\nu$ becomes tighter.
