On November 11, during the Chinese Youth Football League Men's U20 Championship playoff, the Zhejiang team made a comeback to defeat Shanghai Shenhua. A conflict broke out on the field after the match, escalating into a brawl involving weapons. Online reports suggest the incident was triggered by a ball boy taking a water bottle belonging to the Shenhua goalkeeper, which contained notes on opponents' penalty kick habits. Fans from both sides in the stands threw objects at each other and engaged in physical altercations, leaving one Zhejiang fan with a head injury who was subsequently taken away by ambulance.
