I think it's only fair to stick to the rules of the competition.The original rules have already stated that the top 8 players will qualify for the quarter-final and it should be honoured. Whether 卷心菜 turns up or not should not be used as a consideration to admit Chen Jing Ling to the quarter-final. This holds true even for international competitions. If a sportsman is absent from a match for whatever reason, it is considered a walkover and that no replacement is allowed.
