Most of Wallace Huo's signature photos are printed. A famous star has many things to do every day, such as filming, receiving advertisements, participating in Shang Yan, catwalking, singing and so on. The activities are full. He has to do all kinds of training, recite lines, practice acting, stay with his family and friends, and do some spare time. How can hundreds of photos and posters be autographed by himself? This is not tiring.
