Huang Shu's ex-boyfriend Zhang Xu has been harassing her on a motorcycle while waiting for the bus. In addition, Zhang Xu also knows the nightclub where Huang Shu dances, and has been silently watching Huang Shu, waiting for Huang Shu to come to their senses and protecting Huang Shu and Feng Shi when they are bullied by gangsters.
Grandma Zhang Xu told me that Zhang Xu went to Shenzhen and was killed. In fact, there is no Zhang Xu in the novel. However, combined with the description in the novel, Yin Peng and the driver Johnson fled after learning that Uncle Huang had died. However, Yin Peng pretended to go abroad, but actually stayed in his place, making it dark under the light, while Johnson fled to Shenzhen and was introduced to Yin Peng's brother's company as a driver.
