Some citizens launched "lunch and you" protests in multiple districts, calling on citizens to fight the Coronavirus while not forgetting the 2019 Yuen Long attack. In response to news of a police officer having been diagnosed with the virus, citizens in all districts brought champagne or beer, and said the slogan "The Most Important People Are Something". In addition, outside Causeway Bay Times Square, more than 20 pro-government supporters held Chinese and Hong Kong flags, and played the national anthem. This caused dissatisfaction among the anti-government protesters present, and the two sides broke out in a clash and some people were injured. Police arrested one man and two women in a fight and hunted down another middle-aged man involved in the case. The injured were sent to hospital for treatment.
