PIS

Yan Jun Bu, better known as PIS or YaphetS, is a Chinese professional DotA player admired by many for his great reflexes in game, and notably known for leading his team Nirvana.cn to the World DotA Championship title in 2010. He is most notable and famous for his use of the hero Shadow Fiend, and is considered one of the greatest solo mid players in the game.

Early Years
The first time YaphetS came into public attention is the time his replays are continuously uploaded in sGamer.com, which received comments on being self-hyped. YaphetS himself had arguments on the forum causing him to be publicly disliked. In February 2008's CDL tournament, YaphetS and his team Sison competed and won the first match. However, in the later match, his team was caught cheating and was disqualified. YaphetS, being the team captain, suffered from public criticism. Soon after, he disappeared from the dota scene.

In May 2008, an old school Chinese team maGe reformed with YaphetS as the team leader. In an interview by sGamer.com he stated that "I want to say that our plans is to not play just within China, i think we will flourish internationally." This was regarded as overly arrogant by the community due to the team's less than ideal results. The team soon disbanded afterwards.

cYc
September 2009 in a WCG regional qualifier, Yaphets performed brilliantly, and caught attention of several teams. Less than a month later, Yaphets joins professional team cYc, and the team was able to challenge top teams such as EHOME and CH at that time. However, a wrong move by the manager sealed their fate as they disbanded. He lost to devilnam.

Guangzhou5
By the end of 2009, YaphetS joined G5. G5 did not last very long, and Yaphets still lacks the qualities of being a professional player. After his fatal mistake in the AWTV match against Russian team Rox.Kis, G5 split up and disappeared.

CityHunter
To continue his professional dota career Yaphets joined CH in 2010. the YouTube movie "Perfect is shit", which emphasized on his great reflexes and moves in the game, raised Yaphets' popularity to the top. However, a conflict between the team members, DGC and LongDD, has eventually caused YaphetS to side on DGC and leave CH.

Nirvana.cn
YaphetS joined Nirvana.cn after leaving CH, taking over xiami and zippo. A win in the World Cyber Games China 2010, followed by second places in several tournaments during the domination of EHOME. They stood at the top of the international dota scene, winning the World DotA Championship by beating Deity in the finals. He won a 1v1 showmatch in an precedently undecided tie between him and YamateH as the best Shadow Fiend in the world. Nirvana.cn also won the Razer Global Challenge, with many Europeans participating in the tournament.

DK
At the start of 2011, big-spending DK invited YaphetS to join their galactico squad. However, they underperformed throughout the first 6 months as YaphetS finally retired from professional DotA at the conclusion of the G-League season 1, where DK placed second.

Retirement
During his retirement, YaphetS produced first-person videos on youku on his DotA games.

Return to Competitive Play
YaphetS returned to competitive play in October 2013 by joining TongFu's third team to play in the Nexon Invitational Super Match.
