Having assumed the identity of the eldest daughter of the Bai family, Bai Peiluan would, of course, inquire about everything that the real daughter had experienced to avoid being exposed. Therefore, Bai Peiluan knew her long-lost sister's life story better than her sister herself.
Her sister's mother passed away early. When her father remarried, the stepmother showed no love to her sister, leading her sister to develop severe autism. Fortunately, her grandparents treasured her. Alarmed by their granddaughter's deteriorating condition, they decided to take her in and care for her. From then on, her sister was raised by her grandparents. She didn't want to go to school, so her grandparents hired the best tutors to teach her at home.
Her sister's reputation as a master in music, chess, calligraphy, and painting was spread by her tutors, well-known masters from all over the country, who often showcased her artwork.
