<div>一、CentOS系统访问 g.cn ，发现中文乱码。
于是用以前的方式：yum -y install fonts-chinese
CentOS系统安装后，还是不能显示中文字体。我使用 gedit 编辑源码，其中文注释也为乱码。
后来，终于找到以下方法可以解决，需要两个中文支持的包：

<div>触发器(trigger)：监视某种情况，并触发某种操作。
触发器创建语法四要素：1.监视地点(table) 2.监视事件(insert/update/delete) 3.触发时间(after/before) 4.触发事件(insert/update/delete)
语法：

视错觉现象是双眼跟我们开的一个玩笑，而我们往往还心甘情愿地接受我们看到的假象。其实不止如此，视觉错现象的背后还有一个重要的科学原理——格式塔原理。
格式塔原理解释了人们如何以视觉方式感觉物体，以及图像的结构，视角，大小等要素是如何影响我们的视觉的。
在下面这篇文章中，我们首先会简单介绍一下格式塔原理中的基本概念，</div>
