The picture book tells the story of a pair of siblings who lost their parents and two who lived together. The elder sister earned money from her excellent paper carving skills to read to her younger brother. Two years later, the younger brother was adopted by rich relatives because of his intelligence in reading and took him to other places. My sister saved a scholar in the market and gave him money to go to Beijing to take the exam. My sister went to the Jia family to work and was robbed as a concubine by the merchants. The elder sister refused, so she sneaked out to the government office to drum and complain. The younger brother was the new county magistrate and was supposed to be fair. The merchant bribed the magistrate and discussed with the magistrate to forge the deed of sale. When the case was reexamined, the siblings recognized each other. At that time, the scholar saved by my sister became a patrol. An unannounced visit came here to retry the case. My sister did not favor favoritism and just reported it. She asked the patrol to handle it impartially. Finally, the patrol cut her younger brother into a civilian and followed her sister home to work in agriculture. My younger brother finally understood that one should uphold the righteousness of one's heart, keep one's heart and stop one's actions in order to achieve stability.
