"一夜七次郎" (Yīyè Qī Cìláng) seems to be a transliteration of a Japanese phrase, which literally translates to "Seven Times Wolf in One Night" in English. However, this phrase does not have a widely recognized or standard meaning in either Japanese or Chinese cultures. It might be a name, a title of a book, movie, or song, or a slang term that is not commonly known.

If you could provide more context, I would be better able to assist you with your query.
