f1.pdf

But it's normal when I export the figure as tiff format.

It works ok for me using the latest version of export_fig on Windows - see attached file test.pdf. test.pdf Perhaps your installation of ghostscript or Matlab do not have access to the SimSun font, or perhaps you run the code inside a live script and not in a standalone file or the Matlab console, I don't know...
