春节假期临近，不少公众都在购买春节返乡的火车票。有旅客认为，12306平台每日取消3次订单后就将 限制购票的规定不合理，也有人分享了通过第三方购票平台"破解"限制的方法。 记者实测后发现，在12306账户因三次取消订单被暂时锁定后，通过第三方平台可加价购买到车票，但 如果需要退票，第三方收取的相关服务费难以退回。 铁路部门明确表示，相关账户被限制购票后，乘车人仍可通过亲友账户代为购票，或在火车站窗口线下 购票，无需支付任何额外费用。 账户被限制购票后，仍可通过亲友账户代买 "三次取消订单后12306将限制当日购票"是否为今年的新规定？其制定初衷又是什么？ 记者注意到，在网络平台上也有网友分享12306账户因取消3次订单被锁定后的"破解"方法。有网友称， 可以通过第三方平台进行购票，但不能选择已被锁定的12306账户登录，而是选择"付费抢票"，这样就 可以避开"购票限制"直接进行购票。 这样的方法是否可行？又有哪些风险？记者也进行了尝试，在通过12306平台三次取消订单后，记者的 12306账户被锁定限制了购票权限。 此后，记者通过某第三方平台购票，该平台提供12306账户购票、优享购票等多种购票方式，其中，使 ...

【#段永平谈茅台涨价#，#段永平回应腾讯股价大跌#】2月3日，知名投资人段永平在投资交流平台雪球 上表示，"'据介绍，仅一个月，i茅台平台系统已成功拦截各类异常行为5.4亿次'，这个其实就是有人在 用软件抢单，这会让普通老百姓很难抢到。技术上也许是有办法的，比如同一个人（iP）一个月内不能 买两次。另外，要是一直抢的话（目前这个价位我估计会一年抢到头），茅台也许应该考虑每年温和涨 价，比如每年涨个5%-8%？茅台是有涨价能力的，以前这种能力被价差和假货给侵蚀掉了。"对此，有 网友表示："每年涨5%，那么开瓶率估计会很难看，各种人都会买来囤着等升值，它每年涨1%还相对 合理。"段永平进一步解释："1%太少了，至少要和通胀持平的。每年温和涨价比每几年涨一次要好很 多。茅台过去大概是每隔几年涨一次价，我觉得那样似乎会更费劲一些。涨多少合适是要去摸索的，也 许每年涨3%-5%可能更合适？无论如何，涨多少都应该跟通胀匹配，多了少了可能都不合适。"此外， 还有网友提问："大道老师，刚刚腾讯闪崩您怎么看，对最近的元宝撒红包怎么看，您目前还看好腾讯 吗？"段永平回复："山崩地裂地掉了3%？不要叫我老师，你压根儿就没打算学点啥 ...
