The House Association of Choi Kai Yau College has organized the annual Christmas carnival in mid-December. Different from previous years, the event was held in the courtyard and College Fellows (non-resident and resident) were invited to participate in the activity. There were a number of student performances and game booths; many non-local students said that they could feel the unprecedented Christmas atmosphere in the College. During the event, the College strictly complied with the epidemic prevention guidelines, which included to regulate the number of participants strictly, to wear masks and to keep social distance, so as to bolster the first line of defense against the epidemic while having fun with each other.
