In the ongoing recall campaign against Kuomintang legislator Yan Kuan-heng in Taichung's second electoral district, volunteers reported being threatened by a man on the morning of the 31st while collecting signatures outside a supermarket in Wufeng. The man, wielding a safety helmet, threatened to resort to violence if they did not leave and made derogatory remarks about the recall effort, causing fear among two female volunteers present. They later decided to file a police report, while the Yan Kuan-heng volunteer team condemned all irrational statements made against them.

Opponents of the recall shouted, "Damn the recall law!" One female volunteer responded, "Don't come too close; it will lead to trouble." The man threatened, "I can see you are scared. You better leave right now or I will hit you." He continued approaching the female volunteer while cursing and using obscene gestures, taunting, "We are all Chinese!" to which a volunteer retorted, "I am not Chinese; I am Taiwanese!"

One volunteer expressed feeling anxious when the man returned and quickly recorded the incident on her phone, stating, "I have to do my job here." Team spokesperson Lin Hsuan-hung noted that volunteers often face provocations from individuals with differing political views, but the severity of this man's threats was particularly distressing. In response to this incident, the Yan Kuan-heng office condemned all irrational statements and confirmed that the volunteers intended to report the verbal insults to the police.
