<script type="text/javascript">
		$(document).ready(function(){
	    		var ua = navigator.userAgent.toLowerCase();  				
			    if(ua.match(/MicroMessenger/i)=="micromessenger") { 			       
			        //alert("true");
			    } else {
			    	//alert("false");
			    	window.location.href="http://2014.chinayq.com";
