You can just search the complete works of Tony Jia, which are all movies starring him. Recently, there is "Kill the Wolf 2" co-produced with Jason Wu, Max Zhang and Louis Koo, and there is also a movie called "Trade in Skin", which can also be seen. His movies are basically available on major websites. Even if you don't have them, you can Baidu them out and search for them yourself. I recommend a player called Watch Every Day, which basically contains the latest movies and new ones, but most of them are gun versions. If they are previous ones, you can watch them directly online. Ask for adoption!
