Yo Chow collected all the items she found in a sports ground over a twelve-hour period and placed them in a compression bag, noting the time each item was collected. The items include various personal belongings in addition to sports equipment. Due to the lack of dedicated sports venues in Hong Kong, many sports grounds are, somewhat unintentionally, used for multiple purposes. As a result, people often share the same court with others who are playing different sports or using it for completely unrelated activities, such as drying bedsheets.
