新手做的jquery倒计时，求大神精简代码指正

//容器 Li0、Li1、Li2、Li3、Li4、Li5不可修改 其他任意添加
<ul id="Timer">
    <li class="Li5"><div class="liDiv"></div></li>
    <li class="Li4"><div class="liDiv"></div></li>
    <li class="Li6">：</li>
    <li class="Li3"><div class="liDiv"></div></li>
    <li class="Li2"><div class="liDiv"></div></li>
    <li class="Li6">：</li>
    <li class="Li1"><div class="liDiv"></div></li>
    <li class="Li0"><div class="liDiv"></div></li>
</ul>

//无缝时间表示数字  加到网页最下面或者任意地方
<div id="Timera">
<em class="Em0">0</em>
<em class="Em1">1</em>
<em class="Em2">2</em>
<em class="Em3">3</em>
