Lee Sai Mun

Sean Lau Ching Wan

This young man later becomes one of the most significant individuals in history, as the second emperor of the Tang Dynasty. As the second son of Lee Yin, he respects his father and tries to avoid conflict with his conspiring brothers, Kin Sing and Yuen Gat. On the other hand, he gets along great with Yuen Pa.

He is wise, decisive, and always knows which advice he should listen to. He holds admiration for Cheung Sam Long and receives a lot of help from him, along with Lee Jing and Cheung Chut Chun. He is always able to keep cool and control of things, except for one - Mo Kau - whom he doesn't quite know how to handle.
