Existing studies have explored parental play beliefs in the developed coastal cities in mainland China, leaving parents in developing areas unstudied. This study aimed to understand how these understudied parents view and engage in their children's play at home, using Bronfenbrenner's process--person--context--time (PPCT) model. Eight families were interviewed and observed to explore parental beliefs and practices regarding young children's play at home. Thematic analysis showed that most parents appreciated the importance of play in children's early development but did not know how to scaffold their children's play activities. In addition, the high SES families supported child-led play (i.e., free play), whereas the lower SES families adopted traditional rule-based and adult-driven modes. Therefore, more parent education programs and support should be provided to lower SES families in these developing areas.
