英语翻译我们已经联系过我们的货代了.当时货代告诉我们APL是艘快船,所以我们才定的舱.我们也没想到APL船会走的这么慢.

We have contacted our agent.
The agent informed us at that time that APL was a vessel which would take a speedy route.That was why we booked their container.We never imagined that the route which the vessel took was so slow.
Owing to the spring festival holiday,only one vessel was arranged to depart from Tianjin and Shanghai respectively.The suspension of all shipping services during the spring festival holiday also affected all the shipping schedules nearby.

We have already contact the shipping agent.
Before we booked the shipping space, we had confirmed with the agent that it would be a fast one. We have not thought that it is so slow.
后面的说不通吧，我觉得外国人不会相信的。找个更好的理由，我觉得要。
