In July 2009, a post about a beautiful female classmate driving a BMW Z4 sports car to class went viral on the internet. The original post was reprinted on multiple forums, sparking discussions about the "BMW girl." There were 356 comments on the post on Phoenix News, and it was viewed over 4 million times. "Posing for the camera," this was the reaction of many netizens after seeing the photos. Some netizens believed it was a publicity stunt, while more expressed their envy of the BMW girl or the BMW Z4.
According to netizen leaks, the incident occurred at the Nanrui Building of Minzu University of China. The real name of the BMW girl is Zhang Yunxi. According to students from Minzu University of China, Zhang Yunxi seems to be studying law, but later, another netizen said that Zhang Yunxi is a student at the Continuing Education College of Minzu University of China. As for the poster's claim, they often see Zhang Yunxi in the library and cafeteria, feeling that although Zhang Yunxi is stunningly beautiful, she is quite low-key.
