“序”如何正确翻译成英文？

Do you know how to ask a question in chinese?

There are a variety of 序言 in chinese, what do you want exactly?

Prologue. Only use a prologue in fiction. It comes BEFORE the actual beginning of the story to introduce characters or to explain past events or history that might need to be explained, or to generally intrigue the reader. It's a great place to provide information relevant to your story without have to go through flashbacks or torturous dialogue in your first few chapters. Keep it short. Bear in mind many people skip it!

Foreword. A foreword (NB NOT 'forward'), are words BEFORE the main text which are NOT written by the author. Someone else tell readers WHY they should read the book. This is the place for a guest celebrity or author to praise and introduce the book. It should make an emotional connection with the reader. A foreword should always be 'signed off' by someone other than the author.

Preface. A preface explains HOW the book came about. It is similar to a foreword, but it is written BY the book's author.
