传说中，月老是掌管男女婚姻之神。每年七夕，七星娘娘会把人世间未婚的成年男女制成名册，向天庭呈报。月下老人收到名册后，按照个性、善恶、兴趣与条件抄写成一本配偶名册，然后用红线绑牢男女二人之足，使合适的男女配成一对佳偶。

在一个古老的小镇，有一条古老的小河横穿这个镇南北，把这个小镇划分成东西两个部分。这个古老的小镇保留着一个古老的风俗，所有未婚男子都住在这条河的西岸上面，所有的未婚女子都住在这条河的东岸。

今年月下老人收到了这个小镇上所有未婚男女的名册，他把每个人的个性、善恶、兴趣与条件做了一个简单的汇总，给每个人添加了一个如A B C之类的标签，只有相同标签的男女才有可能用红线绑在一起。原本这个是个很简单的事情，但是现在问题是月老使用的红线，是不能互相交叉的，否则后果会很严重。所以月老为了更多人的幸福，他只能牺牲部分人的幸福。现在月老在纸上笔划了很久，还是没能比划出一个最好的方案，使得让最多对情侣终成眷属。您能帮帮他么？-According to legend, Yue Lao is in charge of the god of marriage between men and women.
