Chen "Zhou" Yao is a semi-retired professional Dota 2 player from China who most recently played for TongFu.
A former member of team Catastrophic Cruel Memory, Zhou was picked up by Invictus Gaming in August 2011 as the latter organisation purchased CCM. He attended The International 2011 along with SanSheng, xiao8, DDC and Ferrari 430, where he placed fifth/sixth and shared a $35,000 prize with his teammates. A year later, Invictus Gaming was invited in The International 2012 as well, with Zhou leading a roster comprised of Ferrari_430, ChuaN, Faith and YYF. They achieved a nearly flawless 13-1 record in the group stage and defeated Evil Geniuses in the playoffs first round, only to be sent into the loser's bracket by the reigning champion Natus Vincere. They nonetheless made it to the grand finals at the expense of EHOME, Team DK and LGD Gaming, and ultimately defeated Natus Vincere in order to secure the $1,000,000 champion's prize.
After a not as impressive performance at the next International, The International 2013, Zhou was removed from iG's roster. A few days later he was announced as new carry player for TongFu.
On February 10th, 2014 Zhou announced his retirement. 
- ↑ ChuaN wasn't able to attend the event due to being from Malaysia (since WCG's rules require that all members of a roster share the same nationality, i.e. Chinese in iG's case). He was subsequently replaced by ChisBug for the duration of the event.
