帮我翻译成英文。

有一个城堡，里面很肮脏。国王一家决定聘请一个清洁工，但过了很多天，都没有人来应聘。国王就和两个下属一起清洁城堡。不料，被女王发现了。女王坚决不让国王这样做，她决定出去旅游，回来后要看到城堡干净整洁。她还派国王出去解决一些问题，还让公主留在城堡看家。一天，城堡来了三个蒙面清洁女工，他们说是来清洁卫生的。过了几天，公主觉得他们是小偷。就把他们锁起来，但知道了他们是国王和两个下属，公主威胁国王。最后他们都很开心。（语法要准确，不要用翻译器翻。。。）

Once upon a time, there was a castle, which was very dirty. The King's family decided to hire a janitor, but nobody applied for this job after many days. The King started to clean up the castle with two of his people. While the Queen insisted not allowing the King to do so after she found out. She decided to go out for a trip and wanted to see a clean castle when she came back. She also sent the King out to solve some issues and had the Princess take care of the home. One day, three janitors with masks on their face show up, claiming they would do the house cleaning. But the princess locked them up, since she believed they were thieves after serveral days. She threated the King after knowing they were the King himself and the two poor guys. At the end, they were very happy...
