After the Guangxin Road crossing incident, Shanghai police arrested those involved, including Xu Guoming, Bian Hanwu, and Yan Xuerong. English-language materials say 11 people were arrested at the scene; the claim of dozens of arrests and nighttime raids from June 7 to 9 could not be verified.

The incident is known as the "Guangxin Road Crossing Incident" or the "Shanghai June 6 Incident."
In the early morning of June 5, 1989, students from some universities in Shanghai set up barriers and sat on the tracks around the Guangxin Road crossing on the Beijing–Shanghai Railway to obstruct rail traffic in protest of the June Fourth crackdown; more than 47 passenger trains were disrupted that day.
