Be sure to write in English, and it is best to add the name of the star you want to write before the address. This will lead to a higher response rate. Write your address in English on the envelope, but write your Chinese address on a small piece of paper, and indicate this is your Chinese address in English on the back of the paper, so that the reply officer of the other party can post this small piece of paper with Chinese address in his reply to you. Put the note and the letter together in the envelope.

I suggest you buy yourself an internationally accepted reply envelope. Manchester United's response rate is particularly low. Comparatively speaking, the response rate of Arsenal in Premier League is very high. It is difficult to get a reply if you don't pay the postage.

I won't go into details of other letters. You must clearly put forward your requirements at the end of the article, such as whose autographed photo you want and what souvenirs you want. But don't mention such heavyweight things as jerseys, which is not good.

The letter has been sent, so don't expect too much. For a novice like you, 4 or 5 replies to your 1 are good.

Good luck.
