When I updated fontconfig, I got file existing conflicts. Force option works fine except bringing warning such as ""/etc/fonts/conf.d/44-wqy-microhei.conf", line 6: Having multiple values in <test> isn't supported and may not works as expected". Then I had to update
<test qual="any" name="family">
<string>WenQuanYi Micro Hei</string>
<string>文泉驿微米黑</string>
<string>文泉驛微米黑</string>
</test>
to
<test qual="any" name="family">
<string>WenQuanYi Micro Hei</string>
</test>
<test qual="any" name="family">
<string>文泉驿微米黑</string>
</test>
<test qual="any" name="family">
<string>文泉驛微米黑</string>
</test>
