The newly installed CentOS does not have Language Support by default. Therefore, it is very difficult.
Finally, we found an effective method:
Su root
Yum install "@ Chinese Support"
Exit
Set Input Methord.
Last step: log out and log on to the user again.

Install Language support in CentOS 5 or Red Hat Enterprise Linux
By Vivek Gite on June 15,200 7 · 8 comments
Q. How do I install installation ages in Linux after installation? I don't have any language specific support installed but need to install the same. I'm using both RHEL 5 and CentOS 5.
A. yellow dog Updater, Modified, a package manager for RPM-compatible Linux systems such as CentoS 5/Fedora 7 and RHEL 5. yum's repository system is quickly becoming the standard for RPM-based repositories.
If the versions were not installed during the installation, the same can be installed by YUM command. Use following command to install Hindi and Chinese support.
# Yum groupinstall {LANGUAGE-support}
# Yum install "@ Hindi Support"
# Yum install "@ Chinese Support"
Use yum grouplist list available groups and ages.
