帮忙翻译成英文,在线等,别用google.谢谢了中国海关强制部分退回,理由是一次邮寄数量过多,要求每次邮寄不超过3双,所以只能将一部分退回你那里,然后重新发给我,我很无奈,谢谢

China Customs enforced to return one part while the reason is excess for single posting quantity and per posting is no more than 3 pairs.so I have to return one part to you and then you may post to me later. I'm so sorry about this.thanks

They are driven back partly by the China Customs, for the reason that the number of mails each time exceeded the limit, which is no more than 3 pairs. In this case, part of the mails are returned to you and please send to me again. I am sorry for putting you to inconvenience, and thank you again.
楼上那些貌似是机译，某些地方文法不通。想问一下原文的“部分退回”实际是退回什么？那个“什么”可以换到翻译中的mail，这样会比较清楚。有什么问题，大家再讨论交流~
