The incident occurred during the deciding game between Taiwan's Lin Yun-ju and Japan's newly ranked world number one, Sora Matsushima. Having recovered from a 0-6 deficit to trail 9-10, Lin was preparing his serve when Matsushima shouted and pointed to the stands, indicating a flash. Matsushima abruptly halted play without signaling the umpire, resulting in a yellow card. When play resumed, Matsushima won the final point on a counter-attack, securing an 11-9 victory and denying Lin his first WTT Smash title.
The interruption initially sparked controversy. Lin's agent took to social media to criticize the sudden disruption, suggesting it could have been a "dirty tactic" that startled both viewers and the server. Fans subsequently accused Matsushima of employing unfair methods to win.
However, video footage that surfaced on Tuesday confirmed a camera flash went off three times in the stands facing Matsushima just as he prepared to receive the serve. The source was identified as Taiwanese junior players who were in the city to compete in the Beijing Youth Smash.
Hung Chi-po, former head coach of the Songshan High School team, clarified that the junior players were recording the match and had accidentally left their flash on. He emphasized that the interference was completely unintentional, adding that the young athletes are deeply remorseful and have been provided with psychological counseling since returning to Taiwan.
In a public statement, the joint Songshan-Chengzheng table tennis team apologized to the players, coaches, and on-site staff affected by the disruption.
"We extend our most sincere apologies for the disruption and impact caused by the use of the camera flash during the 2026 Beijing Smash men's singles final," the organization stated.
The team added it will use the incident to educate its students on the importance of respecting competition rules, maintaining venue order, and taking responsibility for their actions to prevent similar incidents from occurring in the future.
