Yi-Online gamers first choose their game characters based on their respective zodiac. Each zodiac is special in its own way and it affects the future game play of your character. After a series of beginner's game introduction, the game character's role may evolve as a civilian, policemen or triad member. Each role play has its unique game character advancement structure, allowing Yi-Online gamers to experience a realistic, modern lifestyle game play.
