Recently, Zheng Lian, a Changzhou girl born in 1998, became popular on the Internet. Unlike other girls of the same age that attract people's attention through singing and dancing, she relies on many award-winning welding techniques. Because there are relatively few girls engaged in welding, many netizens jokingly call her "female welder".

In addition to the red color of the chemical protection mask, there are chemical smells everywhere, thick work clothes and blazing welding workplaces, which seems to have little to do with a young girl.
