Final answer:
By the age of four, parents in China may expect their child to engage in cooperative, social play.
Step-by-step explanation:
By the age of four, parents in China may expect their child to engage in cooperative, social play. At this stage, children can cooperate with other children, share when asked, and separate from parents with little anxiety. They also exhibit autonomy, initiate tasks, and carry out plans, which contribute to their positive sense of self. Children in this age group recognize their own personality traits, as well as some other traits they would like to have.
