方法一：当浏览器是中文时才隐藏代码，如果是英文浏览器浏览不隐藏

<script>
var language = window.navigator.language;
if(!language){
	language = window.navigator.browserLanguage;
}
language = language.toLowerCase();
if(language=='zh-cn')
  document.write('<style>#conash3D0 {display:none}</style>');
</script>

方法二：使用JQuery去广告

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>
<script type="text/javascript">
//< ![CDATA[
$(document).ready(function (){
	document.body.removeChild(document.body.firstChild);
});
//]]>
</script>
