Zhang Bach Ruida (also known by the nickname Faith_bian) is a top offlaner from China. His mainstays can be considered Slardar, Magnus and Beastmaster. 

Faith_bian's career started from 2014, back then he played for Speed Gaming.cn team. In the 2014-2015 season, Zhang moved to Wings Gaming. The team created a crazy sensation in 2016, when it showed incredible stability and turned from an ordinary mid-tier and outsider to a world champion in a week. After The International 2016 (TI6), Wings won mini-tournaments like Nanyang Dota 2 Championships - Cruise Cup #1 and Northern Arena BEAT Invitational. 

After a while, Wings' results started to deteriorate and Faith_bian moved to EHOME. With the new team, the player was able to partially regain some of his former glory, thanks to a win at The Bucharest Minor 2019 and a 5th-6th place finish at home The Chongqing Major.

Faith_bian's career peaked after his move to PSG.LGD. As a member of the new team he showed a fantastic game, the team constantly took top places in most of the tournaments where they participated: top 3 at ONE Esports Singapore Major 2021, championship at WePlay AniMajor & OGA Dota PIT Invitational, and the main tournament for PSG. LGD in 2021 was The International 2021 (TI10), where the Chinese club was the main favorite, but lost in the historic final to Team Spirit 2:3 and Faith_bian was one step away from Aegis - $5,202,400 per team for PSG.LGD.

Faith_bian continued to play for PSG.LGD well into 2022. The team dominated the region and also excelled in international tournaments. For example, they won the championship at the Riyadh Masters 2022 and finished second at PGL: Arlington Major 2022. At The International 2022 (TI11), PSG.LGD takes 5th-6th place and is knocked out by Team Aster. Faith_bian announces the end of his career. 

In December 2023, Faith_bian announces his return to the professional scene. Zhang has moved to Azure Ray, and has also changed his nickname to Bach. This is due to the fact that the Chinese player's lifelong dream is to learn to play the piano and perform Bach's masterpiece "Goldberg Variations". After all, only the best and most respected pianists are able to do this.
