Her self-defence tactic apparently worked as the uniformed construction workers retreated from her house, as a social media video shows.

The dialect used in the footage suggests that the incident took place in Putian city, south-east China’s Fujian province.

The 53-second-long clip was posted on Miaopai, a Chinese video-sharing platform, by a user called First Hand Video.

The beginning of the video shows the woman, thought to be a local resident, surrounded by almost a dozen workers in camouflage uniforms.

She was not holding any weapon, instead she was waving a used sanitary pad.

The group of men can be heard discussing how to avoid being attacked by the woman as they said: “Where are the shields? The shields?”

Some men held transparent shields at the time.

The furious homeowner, standing in front of a bulldozer on a construction site, was trying to prevent others from operating the machine.

She kept flapping the pad while spinning her body around.

The video uploader did not disclose the time and location of the incident.

However, the woman and others can be heard conversing in a local dialect of Fujian Province.

An official working at the publicity bureau of Putian city told a reporter from the First Hand Video: “Their quarrel was noisy.

“There are no obvious landmarks to suggest the incident was in Putian. Yet they were conversing in our local dialect.”

The official had reported the incident to the local public security bureau, which apparently also had no clue about the attack.
