Do you buy Huang Xiaoming's autographed album?
If you want to sign your autograph, you'd better go to the signing ceremony, so you can kill two birds with one stone by getting it and meeting Huang Xiaoming himself. If you can't go, you can also order his limited edition album, but the price will be more expensive. If you want to be cheap and available, you have to buy it online, but there is almost no autograph, that's what you said. Give it a try, and I wish you an early success!
