Convincing

"Guohong Niu, through yesterday's observation, I found that your major problem is that you have too much of a push-off force," Dai Li said, highlighting Guohong Niu's weakness. Guohong Niu sneered in response.

"I have too much of a push-off force?" Guohong Niu asked arrogantly, "Coach Li, shouldn't a large push-off force be an advantage? The greater the push-off force is, the more sufficient the driving force will be, hence the more acceleration the athlete will obtain. Coaches always comment on the low push-off force of the athletes. This is the first time I've heard a coach complain about a large push-off force. Coach Li, why do you consider this advantage a disadvantage?"
