--- Comment #1 from Peng Wu pwu@redhat.com --- I think maybe good to not change default Chinese fonts by installing fonts packages.
If you want to change default Chinese fonts, please try fonts-tweak-tool.
UMing/UKai fonts are for Traditional Chinese, not for Simplified Chinese.
Compared to Source Han Sans CN, both UMing and UKai are Serif fonts, I think.
