Lui is known to fans as Mr. Lui, or Mr. Him. His last name translates to "him" in English, which led to the title of his book. His foray into writing seemed like a natural extension of his video work.
"I am a director and a video maker. But if you think about it, a camera is a different pen from a traditional pen," Lui said. "I realized that I have always told my ideas, using only a different narrative method, but the gist does not change."
The Bible is a popular subject, although not an easy topic to undertake. However, Lui felt passionate about the project.
