Lu Xing Guang is a man of his middle ages, portrayed with black hair and tiny bits of white hair. His light brown eyes may display a gentle side, unlike other commanders that are commonly serious or sarcastic.
Like many other detective commanders, their attire is modern clothing of a white lab-like coat and black professional pants. Whether they chose to wear their commander uniform or not, the detective commanders can usually wear the Sherlock Holmes' type.
He is known to excel at teaching his students than that of the top two detective sirs, Key Sir of Detective D-8 and Pro Sir of Detective D-10. Because of that, he is usually displaying his kind side than his serious side. However, he can be strict at times, assigning groups of a division between D-4.

His actions are better being examined.
