log file I probably should spend more time getting to read the documentation but I must admit it is too advanced and I have a hard time comprehending what its tring to say.I am on a deadline and need some urgent help. What I want to achieve is to change the title style(font?) to \lishu as described in ctex package page 8

This is my code


But it results in an error saying "undefined control sequence." Please tell me what went wrong here.This is the cnosole feedback

Edit: new log file after updating it to texlive 2020enter link description here edit2:uploaded the result of xetex compile. the link is the same.

  • I'm very upset with CTeX that advertises “fontset=macnew”, which should work in macOS, if I interpret correctly the name. But it doesn't. If I use fontset=windows, then I get an error because simli.ttf is not found.

  • I don't have a mac but based on the code the command should be defined. Is your ctex/tex system up-to-date? Can you show the log-file? Jun 1 '20 at 9:44
  • The command \lishu is not defined with fontset=macnew until ctex v2.5. From the attached log file, you are using ctex v2.4.15. Prior to v2.5, \lishu is defined with fontset=windows|founder only. See related issues (in Chinese): github.com/CTeX-org/ctex-kit/issues/360 and github.com/CTeX-org/ctex-kit/issues/412 Jun 1 '20 at 12:22
  • Use xelatex, not pdflatex

I can ensure you I'm on a Mac, running the latest version of macOS.

If I try your code, I get

! Critical Package ctex Error: CTeX fontset `mac' is unavailable in current
(ctex)                         mode.

which is quite strange. If I change fontset=windows, that error disappears, but pdftex complains that simli.ttf is not found.

So I downloaded simli.ttf from https://github.com/dudongtai2002/Font/blob/master/Fonts/SIMLI.TTF and retried.

\title{\lishu 这是一个标题}



I used \lishu only inside the title, which is probably what you really want.

Now that you added the information that you're running XeLaTeX, the code above runs also with fontset=macnew (no download necessary). Also your code runs with no issue on TeX Live 2020.

I get the error is with TeX Live 2019, for the simple reason that \lishu is only available in ctex-fontset-macnew.def version 2.5.1 or later. See


  • Would you be kind enough to tell me how to check my texlive version. I clicked the texlive utility page and it says Version 1.35

  • @jxhyc Install the new MacTeX. You can see that the log file lists files as belonging to the tree /usr/local/texlive/2019

  • @jxhyc Which engine do you want to use? The first log shows xelatex, but the second log shows pdflatex. Jun 1 '20 at 14:00
  • With fontset=macnew, \lishu is not defined until ctex v2.5.
  • To install ctex v2.5, TeX Live 2020 is required, but from the attached log you are using TeX Live 2019.
  • Hence you can either install TeX Live 2020, or manually define \lishu as following:
\NewDocumentCommand \lishu {} {\CJKfamily{zhli}}
\setCJKfamilyfont {zhli} {Baoli SC}

On macOS, Baoli SC is one of "available for download" fonts. Hence to use it for the first time, a window will pop up to ask for downloading. Just click "Download", and recompile tex file when the downloading is finished.
