xeCJK 使用教程精簡版（點擊下載）：https://github.com/tsingke/xeCJK_demo/blob/master/xeCJK.pdf
xeCJK中可以直接使用系統字體，查看已安裝中文字體，命令行輸入fc-list ：lang=zh-cn
tex 中中文字體引入到 CJKfamilyfont，具體設置命令如下：
\setmainfont{Times New Roman}<span> </span>%缺省英文字體 Times New Roman
\setCJKmainfont[ItalicFont={楷體_GB2312}, BoldFont={黑體}]{宋體}<span> </span>%襯線字體 缺省中文字體為
\setCJKsansfont{黑體}<span> </span>%serif是有襯線字體sans serif無襯線字體。
\setCJKmonofont{仿宋_GB2312}<span> </span>%中文等寬字體
