Direct link rendered image-fail to display Chinese,only display english

Hi all,
I just tried to get Direct link rendered image,but it can not display Chinese,only English.How can I to fix the problem.
Is it possible to install Chinese fonts on the operating system Centos?

I tried to change system language in /etc/locale.conf.

LANG=“zh_CN.UTF-8” SYSFONT=“latarcyrheb-sun16” SUPPORTED=“zh_CN.UTF-8:zh_CN:zh”

And I reboot the server.
But it doesn`t work.
