Hi Ruini,

by the way, maybe this is what you wanted:

==================================
\unexpanded\def\mybig
   {\dosingleempty\dosanhao}
\unexpanded\def\dosanhao[#1]%
  {\iffirstargument
     \switchtobodyfont[#1]%
   \else
     \switchtobodyfont[24pt]%
   \fi}

\setuphead
  [chapter]
  [style={\mybig[44pt]}]

\starttext
\chapter{hello, world}
\stoptext
==================================
