A group of sanitation workers sparked widespread discussion due to their unusual cleaning method on a scorching summer day in northern China.

Video filmed in Dalian City in Liaoning Province on June 27 shows several sanitation workers, clad in sun-protective clothing and hats, kneeling on the ground and diligently scrubbing the zebra crossings with cloths. Despite their clothes being soaked with sweat, they remained steadfast, silently completing what seemed like a straightforward yet challenging task.

The scene quickly stirred debate on the internet. Many netizens expressed admiration for the hard work of the sanitation workers but simultaneously questioned the appropriateness of this cleaning method.

Some commented, "It's too inhumane to make workers kneel on the ground in such hot weather," while others queried, "Is such meticulous cleaning really necessary when the roads get dirty again in just a few minutes with all the traffic?"

In response to public concerns, the authorities explained. They clarified that the sanitation workers resorted to manual scrubbing because there were stubborn stains on the zebra crossings that couldn't be removed with high-pressure water jets.

However, acknowledging the potential health impact of this method on the workers, they have decided to discontinue the practice of kneeling to scrub the crossings.

近日，辽宁大连，环卫工人在高温天气下跪地擦拭斑马线，这一不寻常的清洁方式引发了广泛和热议。

据了解，事件发生在6月27日，正值辽宁大连的夏季高温天气。视频中，多名环卫工人身穿防晒服，头戴防晒帽，手拿抹布，在斑马线上跪地认真擦洗。尽管汗水已经浸湿了他们的衣服，但他们依然坚守岗位，默默完成着这项看似简单却充满挑战的任务。

这一幕迅速在网络上引发了热议。许多网友对环卫工人的辛勤付出表示敬佩，但同时也对这种清洁方式提出了质疑。有网友表示：“这么热的天，让工人们跪地擦地，简直太不人道了。”还有网友认为：“这样的精细清洁真的有必要吗？马路上车来车往，过几分钟不就又脏了吗？”

面对公众的质疑，相关部门给出了回应。他们解释称，此次环卫工人之所以采取这种清洁方式，是因为斑马线上存在一些顽固污渍，这些污渍用高压水枪难以清除，因此才决定让环卫工人进行手工擦拭。同时，他们也意识到这种工作方式可能会对环卫工人的身体健康造成影响，因此已经决定停止这种跪地擦洗的清洁方式。
