不够犀利就找个外挂吧 --------------------编程问答-------------------- 真的是买不到了票了，就连站票也预定不了啊 555555555555555555555555 --------------------编程问答-------------------- 问下怎么样可以预定到无坐的火车票啊
-----------------------
不好意思，刚看到私信。
预订车票，一般都是电话或者网上订票的。
你想订票，打电话或者网上查看一下就可以订票了。 --------------------编程问答--------------------
如果订票没有，买票没有。只能曲线回家了。
买就近的火车票，然后导车回家吧。
好运。 --------------------编程问答-------------------- 这么惨 出去不要说是搞it的~
