Jia Baoyu took the initiative to admit two things: Rose Dew and Poria Cream, in order to save Wuer who had been wronged and Caiyun who dared to admit it despite stealing, and to prevent things from making a big fuss, which reflected Baoyu's caring and equal personality.
Pinger spared Wuer and Cai Yun when she knew the truth. When Wang Xifeng proposed severe punishment, she persuaded them in good faith.
In the end, it's settled, which shows Pinger's generosity, erudition, the overall situation, kindness to others and cleverness.
