According to my experience, Real Madrid's reply rate is 100% (at least they have replied to all my letters), but the reply is usually a printed letter and a family photo. If you want to get the star card and signature, you need the quality of the letter. If you can send a small gift, you can increase the probability of receiving a reply gift. There are many successful examples in China. Real Madrid sent many signature cards. English is ok, but Spanish is better. Florentino attaches great importance to the Asian market. Someone once wrote to him and gave him advice, and got a reply from Qi Zu, Kathy and others.
