Food delivery worker, Chen Guojiang — or Mengzhu, as he is more widely known — was arrested on February 25, 2021, under charges of “picking quarrels and provoking trouble”. Mengzhu is deemed to be one of China's few remaining labor organizers, and has called for collective action against powerful e-commerce companies, demanding better pay. As an advocate for delivery workers’ rights, Chen posted videos which called out platforms for allegedly oppressing workers and violating laws and regulations by fining drivers for late deliveries, and called on the government to increase regulations for the gig economy. It is reported that Chen said that he managed 16 WeChat groups reaching over 14,000 delivery driver contacts. He called for drivers to stop work when faced with unfair working conditions.
