BEIJING â In their final moments, the passengers screamed.
A woman stood at the front of the bus, slapping the driver with a cellphone. The driver hit back, losing control of the bus and sending it plunging nearly 200 feet into the Yangtze River in southwestern China.
The fight was the talk of China on Friday, as the police released a video, recovered from the wreckage, showing the moments before the crash, which occurred on Sunday in the city of Chongqing and killed at least 13 people.
The video was viewed hundreds of millions of times, eliciting shock, scorn and questions about whether there was too much vitriol in society.
âMaybe thereâs too much negative energy,â Wang Chenshuang, 30, a resident of Chongqing who works in the education industry, said by telephone. âItâs surprising.â
Two people who were on the bus are still missing, and no survivors have been found, the police said.
The authorities said the woman, surnamed Liu, 48, began hitting the driver, surnamed Ran, 42, after she missed her stop and he refused to let her off.
Much of the fury on Friday played out online, where internet users said they were outraged that Ms. Liu and Mr. Ran would allow a petty fight to endanger the lives of so many people. They called on the government to do more to protect bus drivers.
âIn a few seconds, a whole bus of life is lost,â wrote one commenter on Weibo, a microblogging site. âThe price of acting on impulse is too grave.â
Zheng Chuankai, a lawyer with Anli Partners in Beijing, said the incident underscored the need to maintain strict laws to punish those who endanger public safety.
âThis case is very typical and very vicious,â he said.
Previously, state media outlets had blamed a female driver for the crash, whose car collided with the bus before it plunged into the river. Those reports unleashed sexist rants against female drivers online.
But the police on Friday made it clear that it was the fight that had caused the crash, blaming in a statement the âmutual fistfighting behaviorâ of Ms. Liu and Mr. Ran.
âFifteen fresh lives have vanished, and the lessons are extremely painful,â the statement said. âMay the dead rest in peace, and the living be warned.â
After the video emerged on Friday, many women spoke out against those who had initially blamed the female driver for the crash.
âEvery time I see this, it makes me very angry and indignant,â Joy Lin, a gender equality advocate in Shanghai, said by telephone. âWomen are being blamed for mistakes that arenât their own.â
An online commentary by Peopleâs Daily, the main newspaper of the Chinese government, described the dispute that led to the fatal crash as âpointless.â
âWe have to ask, why do fistfights between passengers and drivers keep happening?â the commentary said. âTake to heart the lessons painfully learned, and donât stop at sobbing. And donât stop at anger. There is no redemption without thorough reflection.â
