If you read this letter, you must be an adult. There are some things that I cannot express clearly before my death, not because I don't trust you, but because they are very involved and involve other people's privacy. This notebook records what I have seen and heard in thirty years of maritime trade. Some of the things in it may be helpful to your study of history. Some of the people in the album are related to me, and some are just colleagues. But there's one person you need to pay attention to: photo number 17.
