World champion Qin Haiyang completed the breaststroke treble Friday and Zhang Yufei claimed a sixth gold as China's swimmers sent a final warning shot from the Asian Games ahead of the Paris Olympics.
Their victories were among four titles the hosts snapped up on the final day of swimming in Hangzhou, where they easily topped the table with 28 golds in the pool.
While no world records tumbled across the six-day event, multiple Games and Asian bests were set, some of them eye-popping.
