fc-list :lang=zh
Copy the codeIt is found that there is no Chinese font library, so we need to upload the directory to create the text body library
mkdir /usr/share/fonts/chinese
cd /usr/share/fonts/chinese
Copy the codeSet access permissions for this directory
chmod -R 755 /usr/share/fonts/chinese
Copy the codeClick here to view the Chinese font library
Step 4 Associate the uploaded font library
cd /usr/share/fonts/chinese
mkfontscale
mkfontdir
