High-tech confirmed China U-21's valid goal

Xiang Yuwang's header crossed the goal line but was cleared by an Iranian defender. Although the referee ruled the goal valid, the Iranian coaching staff remained unconvinced, insisting that the ball had not crossed the line. Fortunately, the U21 Chinese national team had employed drone footage for better post-match tactical analysis, capturing the moment of the goal. This evidence finally convinced the Iranian team to accept the decision.
