\usepackage{fontspec} \usepackage[BoldFont,SlantFont,CheckSingle,AutoFallBack=true]{xeCJK} \usepackage{CJKnumb}
with
\setCJKfamilyfont{WSL}[Vertical=RotatedGlyphs,BoldFont=DFT_TX3.TTC]{WSL_Kai_TPS.ttf}
But after some update of the packages my Chinese rotation become invalid.
Anyone know what happened?
