In this essay, I share my experiences and reflection on fighting the COVID-19 pandemic from the perspective of a Chinese student residing in Pittsburgh, USA. Three examples of "commoning"-acts of managing shared resources by a group of people-reveal the importance of care and collaboration in the time of uncertainty. First, when COVID-19 posed a threat to the food supply chain, community gardens and home gardening ensured food security and enhanced mutual support. Second, the emergence of online activities of teaching, learning, and collaborating presented an opportunity of having more collective, equitable, and diverse formats of virtual communities. Lastly, volunteering in the distribution of "Healthy Packs," I witnessed the nurture of a sense of belonging and a connection with home in the student community. These examples suggest that facing the crisis, care-driven commoning activities at the individual, everyday level lay the foundation for large-scale collaborative systems.
