Xiao Yuqian brought him to the cast and crew for the first time. She introduced him to the director but she didn't reveal his real identity. This was to avoid people seeing him in a different light, as she was afraid people would supplant him.
And just like this, Ma Haodong's first appearance on screen came out. He was a full-on disciple of the Beggars Sect. Xiao Yuqian was quite satisfied when she saw his new image. His appearance completely detached from the feel of a rich young man. It kept well in accordance with the image in the script.
After that, Ma Haodong's performance in the studio became even more remarkable. This allowed Xiao Yuqian to feel completely at ease.
People might think that with who Ma Haodong was and the fact that he was under the management of a star manager, the roles he took should be at least secondary male leads or above.
