            小儿呼叫走长街，云有痴呆召人买。
            二物于人谁独无？就中吴侬仍有余；
            巷南巷北卖不得，相逢大笑相揶揄。
            栎翁块坐重帘下，独要买添令问价。
            儿云翁买不须钱，奉赊痴呆千百年。

        汉字：<span id="zhongwen" class="num">87</span> 个<br>
        中文标点：<span id="zbiaodian" class="num">12</span> 个<br>汉字+标点：<span id="zhongwenbiaodian" class="num">99</span> 个<br>
        英文：<span id="yingwen" class="num">43</span> 个 （含英文状态下的数字、符号、标点）<br>
        数字：<span id="shuzi" class="num">13</span> 个<br>
        字符总数：<span id="numwords" class="num">241</span> 个字符<br><br>
        小贴士：汉字和中文标点算两个字符，数字、空格、英文字母，英文标点算做一个字符。<br>
