This group of people was mistaken. Du Yue and the other two had plenty of ways. Du Yue found a large speaker in her space. She plugged in a USB flash drive and pushed the speaker to the entrance of the courtyard. The group of people outside the courtyard were shocked when they saw Du Yue pushing a big black box out in the dark. They thought that Du Yue had found a bomb somewhere and wanted to kill them.
However, their worries were unnecessary. Du Yue did not open the door and walk out. Instead, she placed the speaker next to the fence. After turning on the speaker and turning the volume to the maximum, Du Yue turned around and returned to the RV. This time, after closing the doors and windows, the loud music in the courtyard could still be heard clearly.
