xeCJK 使用教程精简版（点击下载）：https://github.com/tsingke/xeCJK_demo/blob/master/xeCJK.pdf
xeCJK中可以直接使用系统字体，查看已安装中文字体，命令行输入fc-list ：lang=zh-cn
tex 中中文字体引入到 CJKfamilyfont，具体设置命令如下：
setmainfont{Times New Roman}<span> </span>%缺省英文字体 Times New Roman
setCJKmainfont[ItalicFont={楷体_GB2312}, BoldFont={黑体}]{宋体}<span> </span>%衬线字体 缺省中文字体为
setCJKsansfont{黑体}<span> </span>%serif是有衬线字体sans serif无衬线字体。
setCJKmonofont{仿宋_GB2312}<span> </span>%中文等宽字体
