Road cleaners in China are being measured by a new and unusual method.
中国的道路清洁工们正在接受一种与众不同的全新考核办法。
City inspectors have started weighing dirt found on the street, in order to determine how good a job the cleaners are doing.
为了确定清洁工的工作是否做到位，城市考核人员开始给街上的污垢称重。
The exercise started on Wednesday in Xi'an, the capital of the Shaanxi province. Inspectors draw out a random square meter on the street, and sweep up the dust within, placing it on a weighing scale.
这一试行办法于周三始于陕西省会西安市。考核员在街上随机画出一平方米，把里面的灰尘扫干净放在秤上。
Streets which exceed 5 grams of dust per square meter will count as a strike against its cleaner. Three strikes gets the cleaner fired, and their supervisors will face disciplinary action too, reported the state-run People's Daily.
据中国国家媒体《人民日报》报道，街道上每平方米的灰尘超过5克，负责的清洁工就被记一次不合格。三次不合格的清洁工将被开除，其主管也将受到纪律处分。

The new rules have drawn criticism from netizens, many of whom say it's unfair to the cleaners.
