To help his students quickly grasp the essentials of martial arts, Liu dedicated many nights to researching and refining his teaching methods to overcome cultural and language barriers. He demonstrated classic kung fu routines during class breaks and used movie clips to enhance his classes.

Liu enjoys practicing with his students, teaching a range of skills from basic stances to Shaolin fist and saber techniques. He emphasizes to his students that martial arts classes should not focus solely on skills; they should also understand the spirit of kung fu, which promotes self-improvement and virtue alongside physical skills.

"Martial arts classes should not be just about martial arts techniques," Liu said.
