Writing in calligraphy and regular script, should I use Shengxuan or Shuxuan?

Everyone who has ever written calligraphy knows that

Most of the techniques for practicing calligraphy are written in raw form

Whether you write regular script or something else Fonts

Except for small regular script (but there are also masters who write in small regular script)

Only people who can’t write or can’t write well at all

Only then can I write calligraphy with a familiar brush
