This is the first drama I've ever watched!

Basically the back story is that, Good and Evil has always been battling. The representative of the good side (heaven) was Ah Yat's father. His nemesis, the devil king, jealous that he can't possibly win a fight, impregnant Ah Yat's mom with his own demon seed, and plots that when the boys grow older they'll have the most epic show-down because the Good son will probably hesitate to kill his own brother. The devil king and Ah Yat's father have a showdown, which the Devil King gets locked away in a cave, and Ah Yat's father and mother pass away.

Years later the boys grow up along side their adoptive mother, and their sister Kieu Kieu  (**I watched in Vietnamese, so I don't know the Chinese). The three are quite comical, and often get into trouble and fights with each other. The three pretty much tear apart the little village, beneath the mountain, with their antics. Throughout the drama, they'll be introduced into several characters Thanh Thanh (Ah Yat's girlfriend), Yen Phien Thien (Their awesome martial arts friend), and many more characters. Thanh Thanh is a pretty violent/bossy girl towards Ah Yat, but he still tries to pursue her. Yen Phien Thien is a hit-man and the two brothers ask him to teach them martial arts, the three get into a lot of trouble in casinos (by scamming people). Throughout the funny stuff, there are several arcs where they all face the devil king's minion. 

This drama is from the 90's so the CGI sucks on today's TV. It's also quite goofy. But it's a great drama and really showcase all the actors. Roger Kwok and Dicky Cheung were REALLY handsome when they were young. If you get a chance to watch this drama, it's pretty good.
