write(@HELP拍卖规则说明文档：

1. 拍卖过程中银票无效，请先去钱庄兑换成硬通货，如黄金、白银、铜钱。

2. 当有人拍卖物品时，拍卖进程正式开始（拍卖底价不得少于10两白银），此时玩家可以
以至少1两白银（或100文铜钱）的最低差价值参加竞拍，如果一段时间内无人投标，将
进行喊价，三次喊价后仍然无人出价，则拍卖终止。倘若一直有人投标，到了规定时间，
此次拍卖活动仍会被终止。拍卖场最大允许5件物品同时拍卖。

3. 拍卖活动终止后，最后出价者为胜，货款从买者手边及钱庄提取，物品直接转移到买者
身上，如果不堪负重则放在买者所在房间之中，如果房间也无法装下，物品作没收处理，
切记！物主所得款额直接转至其钱庄帐户。拍卖开始时对卖方收取底价2%的手续费。倘
若拍卖过程中始终无人投标，拍卖过程宣布失败，手续费恕不退还物主。拍卖成功，买
卖双方各按成交价交纳10%的中介费。

4. 拍卖过程中，以下行为当作违反拍卖规则处理：买卖双方的任何一人离开游戏导致拍卖
进程中断；物品离开了物主本人；拍卖结束时买方无力偿付成交价。发生上述情况之一，
责任方信誉度会降低，惩罚是一小时内不得参加任何与拍卖有关的活动。如果在禁止拍
卖的时间内再次违规，则禁止时间随违规次数累加。倘若拍卖物品三次喊价之后因为无
人竞标而取消，卖家在两分钟内不得再拍卖其他物品。
