Yep, I'm pretty sure that's Guan Yu.

For those wondering, Guan Yu was a general of legendary prowess during the Three Kingdoms period of Ancient China. He is deified and represents loyalty and justice. Ironically, in Hong Kong, both the police and the triad worship him.

Used to work in a newspaper in Hong Kong and we have a statue of Guan Yu as well...

Anecdotally, the triad worships Guan Yu with black shoes while the police worships him with red shoes.

That's a detail that I did not know!

Yup, that glaive is unmistakable. I knew that hours of playing Dynasty Warriors would pay off.

That glaive (more correctly "guandao") has a name in the Romance of the Three Kingdoms, btw: 青龍偃月刀 (Green Dragon Crescent Blade), also known as 冷艷鋸 (Frost Fair Blade).

EDIT: Guan Yu's horse also has a name: 赤兔 (Red Hare)
