1. It is difficult to attend the signing ceremony of EXO. SM is drawn by drawing small receipts, and some people can't get it even if they buy more (generally 100 people draw).

2. Yes, you don't need to buy it on site, but you can buy it at the Korean video store in advance;

3, an album can be signed by everyone, it is hard to say how many albums you can sign, because there are people in front and behind you, and it is impossible to stay with one person for too long. Generally, one person will sign the next person's name. You can ask them some questions when they sign, or ask him to write something to you. After signing, he has to leave quickly.

4, you can send gifts, just send some small gifts.

I don't know much, that's all, I hope you are satisfied.
