In the past, when I wrote letters to Tom, they were all sent to the Harry Potter crew, but the crew was dissolved long ago, so there is no need to send them. Tom used to have his own address, but that address is no longer valid. Even if he has an address, it's a mass version of the assistant's reply to you. If you ask him to write something, it is more reliable to leave a message on Twitter or Facebook, and he may reply to you, depending on your luck (you go to his homepage, he will reply to dozens of fans every time, whether it is a group, a certified user or an individual), but generally it is thank you, wish you luck or have fun. Another way is that his foreign fans organize some activities for the meeting every year, such as sending postcards to Tom, or taking a picture of Tom's head at a famous scenic spot, developing it and sending it to these fans (I participated in Christmas activities and waited a long time for Tom to get it). ), you can write your words to Tom on the back of postcards and photos, and then those fans will summarize them to Tom. In this case, Tom will not reply to you personally, but will write on Twitter or Facebook,' Thank you for the fans who gave me gifts, love you very much and wish you good luck.' These rarely get Tom's long reply, but two lines are good. It is impossible to write letters. It is an opportunity to leave a message on his official Twitter or Facebook, but if you send something to him through activities organized by Fenfen, it will usually be delivered to Tom, but it will take a long time and only get a general reply from the masses. Anyway, good luck.
