 Professional Career
 Early Career and FTD
Before ZSMJ played DotA, he was a player in another DotA-like game. In 2009, ZSMJ's perfomance in the CDEC led to FTD recruiting him. November 2009, during the SMM Grand National DotA Tournament in Malaysia. 20 minutes into the game against Kingsurf, FTD's Flying Courier containing ZSMJ's Sacred Relic was destroyed by Kingsurf's Beastmaster. Keeping his composure, ZSMJ farmed another Relic in 7 minutes. In the end, with efforts from captain 2009, turned the game and won against Kingsurf. They soon defeated cD in the final and won the SMM.
At the end of 2009, LGD sponsored FTD. In June 2010's ACG Chinese Qualifiers against EHOME, EHOME started off with an advantage, but ZSMJ's Medusa dragged it to late game. By 45 minutes, ZSMJ farmed up a Divine Rapier. However, in 52 minutes, ZSMJ's Medusa died and his Rapier was taken away. ZSMJ decided to buyback immediately and buys another Rapier to end the game.
In August 2011, Invictus Gaming took away 4 of ZSMJ's team members, leaving ZSMJ alone in LGD. LGD was reformed with xiao8 and co., but never recovered from the shock. After WDC in 2011, ZSMJ decided to leave LGD and go inactive.
In December 2012, after a long period of retirement, ZSMJ announced his return to the Dota scene.
 ViCi Gaming
ZSMJ decided not to form his own team due to his lack of management skills. Instead he joined Vici Gaming team 2. On March 28, 2013, he was promoted to Vici Gaming team 1.
