Liu Lu has been practicing Wushu, a form of martial arts, since childhood. He has forged his own two-handed sword, wielding which requires a certain level of flexibility in one's body – its uniqueness lies in dexterity and trickiness. He also runs a Wushu school in his hometown Anqiu City, east China's Shandong Province. "When I had students, I started to think that it is no longer my own business. There's a sense of responsibility and a spirit of inheritance," he said.
