Baidu is enough for the address of the team or football association. If you give it to a player, just add the player's name to the club address. In the past, the football club announced 1, 2, 3, and the addresses were all listed in detail. However, I haven't paid attention to the update in the past two years, and I don't know if there is a new information bug manual. Language processing can be carried out in English writing format. It is suggested that LZ search for sample letters on the internet and write them in imitation of the format. Above all, don't blindly copy sample letters. It doesn't matter if the language is simple, but you must write your true feelings and personal opinions and write your own characteristics. I won't say much about using airmail envelopes. You can put some things with China characteristics in the letter, such as paper-cutting, landscape postcards, etc. To increase the goodwill of the reply officer, but you should focus on the content of the letter and don't think about giving heavy gifts. Finally, I recommend several teams with high response rates to build confidence: Czech Football Association, Manchester United, Arsenal, Liverpool and many teams in the Bundesliga, such as Leverkusen and Hertha Berlin. These are all recognized, and the rest LZ will explore for itself ~
