A big fan of…

In English, "big fan" is a colloquial term that is used to express that someone really likes something or someone. It can also be used negatively to express dislike. 在英语中，big fan是一个口语表达，用来表达某人真的喜欢某物或某人。它还可以用来表示不喜欢。 Just note that saying "I'm not a big fan of sth./sb." is softer and more indirect than saying "I don't like sth./sb." 注意，“I'm not a big fan of sth./sb. (我不是某物/某人的忠实粉丝)”比说“I don't like sth./sb. (我不喜欢某物/某人)”更委婉、更间接。
