He beat Anthony McGill 4–3 in the semi-finals before whitewashing Lü Haotian 4–0 to claim the £10,000 first prize. In the full ranking events, Liang won five successive frames against defending world champion Ronnie O'Sullivan in the second round of the International Championship to triumph 6–4 which marked his first ever success over his opponent having lost in all four previous attempts. He then thrashed Mark Davis 6–1 to reach the quarter-finals of a ranking event for the first time in four years, where he lost 3–6 against Graeme Dott. Liang reached the last 16 of both the German Masters and Welsh Open, losing 2–5 to Mark Davis and 2–4 to Barry Hawkins respectively.
