SJTU Thesis v1.1 如何在sjtuthesis.cls中设置subsection的格式

[CrazyElements]

目的：将subsection 和 subsubsection 设置为小写宋体，缩进 2 字符

我将sjtuthesis.cls 682行起修改为

  section = {%
    format       = \hspace{2em}\zihao{4}\bfseries\heiti,
    afterindent  = true,
    afterskip    = {1ex \@plus .2ex},
  },
  subsection = {%
    format       = \hspace{2em}\zihao{-4}\songti,
    afterindent  = true,
    afterskip    = {1ex \@plus .2ex},
  },
  subsubsection = {%
    format       = \hspace{2em}\zihao{-4}\songti,,
    afterindent  = true,
    afterskip    = {1ex \@plus .2ex},
  },

发现只有section缩进了2字符，并且字体也没有改变，感觉还有其它地方控制这些内容😂
