Jquery如何选择到父父元素下的某个子元素（越多种方法越好）

Question

点击AddSection，给FormItemListEdit2下嵌套某个div，div已经用onclick动态生成

 <div class="FormItemListEdit">
   <a href="javascript:void(0)">
    <p class="EditContent">
    <a href="javascript:void(0)" class="EditContentImg"></a>准备工作
    </p></a>
    <a href="javascript:void(0)" class="RightContentImg"></a>
    <div class="RightContentImgAdd">
    <div class="Entry">
  <div class="EntryTrangle"></div>
  <a class="AddChapter"href="javascript:void(0)"><p>添加章</p></a>
  <a class="AddSection" href="javascript:void(0)"><p>添加节</p></a>
  <a class="DeleteColumn"href="javascript:void(0)"><p>删除</p></a>
</div> 
   </div> 
    <a href="javascript:void(0)" class="RightContentNum">0字</a>
    <!-- 二级嵌套 -->
     <div class="FormItemListEdit2">
   <p class="EditContent">安排行程规划</p>
   <a href="javascript:void(0)" class="RightContentImg"></a>
   <div class="RightContentImgAdd2">
 <div class="Entry">
 <div class="EntryTrangle"></div>
 <a class="AddSection2"href="javascript:void(0)"><p>添加节</p></a>
 <a class="DeleteColumn2" href="javascript:void(0)"><p>删除</p></a></div></div>
 <a href="javascript:void(0)" class="RightContentNum">0字</a></div>

  </div>
