secondhand information二手信息
Information that is not from the original source, but instead from someone who heard it, and who may not be reliable; a formal term for "gossip"
One of my co-workers told me she heard our boss say he's retiring next year, but I don't believe her because I never trust secondhand information.
我的一位同事告诉我，她听我们老板说，他将在明年退休，但我不信她的话，因为我从不相信二手信息。
