About his choice of withdrawal, Lu Guangzu explained after the game: "I felt some discomfort in my lower back before the match, but I still wanted to give it a try. After playing a few rallies, I realized I really couldn’t generate any power, so I just tried to hang in there and rally with my opponent. But eventually, I completely lost the ability to attack, and it became really difficult to deal with this kind of acute strain. I think the recent matches have been quite exhausting, leading to physical fatigue. I’ll need proper treatment once I get back."
