wasted a chance to take the match in the next frame and went on to lose 9–10. Zhang ended the season ranked world number 71. 2010/2011 season Zhang began the 2010–11 season well by defeating Jak Jones 5–4, Paul Davies 5–1 and Stuart Pettman 5–3 to reach the final qualifying round of the Shanghai Masters. He faced Matthew Stevens and was beaten 2–5. However, he could only win more match in qualifying for the remaining six ranking events, concluding with a 6–10 loss to Andrew Pagett in the first round of World Championship qualifying. He finished the season ranked world number 84, well outside of the top 64 who retain their places on the snooker tour. He therefore entered Q School in an attempt to win back his place and was one match away from doing so in the first event, but lost 1–4 to David Grace. He couldn't qualify from the remaining two events and did not have a place on tour next season. 2011/2012 season After being relegated off the tour the previous year, Zhang was confined to entering minor-ranking Players Tour Championship during the 2011–12 season. He played in all 12 of them, but had to wait until the final event, the FFB Snooker Open, for his first win which was a 4–1 triumph over Jamie Burnett. Zhang was beaten by the same scoreline by Stephen Maguire in the next round to finish a lowly 115th on the Order of Merit. Zhang lost in the final of the ACBS Asian Snooker Championship 2–5 to Hossein Vafaei, but as Vafaei had already qualified for the main snooker tour, Zhang received a place for the 2012–13 and 2013–14 seasons. 2012/2013 season Zhang lost in the first round of qualifying for the opening three ranking events of the season. He played in all three of the new minor-ranking Asian Players Tour Championship events, reaching two quarter-finals where he lost to Michael White 3–4 and Li Hang 2–4 respectively. He finished 10th on the Asian Order of Merit, just outside the top eight who qualified for the Finals. His first win in a ranking event match this season was a 6–5 success against Li Yan in International Championship qualifying, but he lost 3–6 to Alfie Burden in the next round. The most matches he could win in qualifying was for the World Open by seeing off Michael Wild 5–3, Luca Brecel
