Just follow the basic format of English. Write something about yourself and how you like Arsenal. Generally, 2-3 pages is enough, and you don't need to write a lot. There are many articles on the internet for reference. My English is poor and I can't give any advice.

I wrote them a letter. I guess they can't read what I wrote. In addition, they gave me two identical copies, including a printed reply from their manager Dunn at that time, and an Arsenal team magazine, which is quite collectible. Arsenal's response rate is not bad. I have been writing three letters to them, and all of them have responded. The printed letters are different in content, and there are also team magazines. As for wanting an autograph or something,

And you can attach some cards with China characteristics to the letter, which will attract their attention, and the address you said. In fact, you can attach a small note with your Chinese address to the letter. When they reply, just paste the note directly, which is convenient for them and the postman.

If you send a letter, you can take it to the post office. They will tell you how many stamps you need, generally 6-7 yuan, the envelope is an international envelope, 1 yuan, which is sold in stationery stores.

Finally, good luck!

Finally, I'll give you the address of Arsenal.
