I fired my boss aka partner

Actually its he who fired me as he has no choice
He is 1 of those typical chinaman boss, has no business ethics & manipulative. the rest of partners & staffs are mind control by him except 1 who is the real boss in the company which i feel sorry for. Right now his top level management morale went down & it affects his business because I've opened another company doing in the same business field & JV with his rival(s). Finally that I managed to break free from the leash, now I need to loose another 1.
