1、安装wqy-zenhei字体

sudo apt-get install ttf-wqy-zenhei

2、修改系统字体配置文件/etc/fonts/conf.d/49-sansserif.conf

打开/etc/fonts/conf.d/49-sansserif.conf这个文件：

sudo gedit /etc/fonts/conf.d/49-sansserif.conf

然后修改倒数第四行的字体为WenQuanYi Zen Hei，如下:

<?xml version="1.0"?>

<!DOCTYPE fontconfig SYSTEM "fonts.dtd">

<fontconfig>

<!--

If the font still has no generic name, add sans-serif

-->

<match target="pattern">

<test qual="all" name="family" compare="not_eq">

<string>sans-serif</string>

</test>

<test qual="all" name="family" compare="not_eq">

<string>serif</string>

</test>

<test qual="all" name="family" compare="not_eq">

<string>monospace</string>

</test>

<edit name="family" mode="append_last">

<string>WenQuanYi Zen Hei</string>

</edit>

</match>

</fontconfig>

3、重启chrome，OK！！！
