In the original work of "Do You Know It or Not, It Should Be Green Fat Red Skinny", Minglan is pregnant, Gu Tingye is crazy with joy, and the Heavenly Garden is happy, but only Sister Rong seems to have a heavy heart, why? Because she heard that her mother-in-law has a child, she will not be good to herself, and even abuse herself, after all, her own existence will hinder the existence of her mother's children. Sister Rong remembered that when she first arrived at the Hou Mansion, every night she would think of her own mother-in-law, Zhu Manniang, and her younger brother Changge, and later she had a mother-in-law, who was very kind to herself and never abused her, but ate and drank well, and sent herself to study. So Sister Rong slowly forgot her own mother-in-law, and later she found that her impression of her mother-in-law and brother was much lighter, and even sometimes she couldn't remember their looks. At that time, she was all Minglan in her heart, hoping that Minglan was her own mother.

Later, Minglan became pregnant, and everyone in the Hou Mansion was happy, but she also listened to a lot of things about the mother-in-law's abuse of the concubine, and she was a little disgusted with the child in the mother-in-law's belly at that time, and she didn't know whether Minglan would be good to herself if she had her own biological child. Later, Sister Rong once listened to Mr. Xue's class, mr. Xue said that others are really good to themselves, and they should thank others for being good to themselves, rather than jealous of each other's goodness, after all, they have benefited from others. When Sister Rong thought of this, she felt that she had stopped her bad thoughts, and then thanked Minglan for her kindness to herself from the heart, no matter what, Minglan's kindness to Sister Rong was real!
Sister Rong wore festive clothes in the courtyard to run during the New Year, and Minglan stood up her stomach to give everyone money, when Minglan saw Sister Rong, she cordially called Sister Rong, and sent a big red envelope to Sister Rong, looking at this heavy red packet, and then looking at Minglan's gentle smile, Sister Rong suddenly released, no matter whether the mother-in-law has children or not, at least the mother-in-law is good to her is real. The blessing of Gu Tingye next to her to Sister Rong is that Sister Rong will study hard and set a good example for her future younger siblings. Sister Rong heard this, her heart was very happy, and in the future, her mother's children would eventually call her sister, and she was very happy in her heart, and even looked forward to the arrival of her brother or sister.
Sister Rong is the eldest daughter of Gu Tingye, the environment in which she lived from childhood is that her father does not love her mother, and she often does not see her father and mother-in-law, and then she comes to her mother Minglan, Sister Rong feels the happiness of childhood, before she was sent to the fence, and later under the shock of Minglan, those people finally took her as a miss, so Sister Rong's final understanding of Minglan is that Minglan is a good mother-in-law, and she must be grateful for Minglan's kindness to her, and she cannot take revenge.
Although Gu Tingye is not a loving father, there is not much communication with Sister Rong, and he is not strict with Sister Rong, so he gives all the things about Sister Rong's upbringing to Minglan, who has no maternal love for Sister Rong, but is willing to be a good mother-in-law, so he is very careful about Sister Rong's upbringing, the teacher who should be invited must be invited, and the knitting female red who should learn must learn, which is a strict requirement. It is very fortunate to have such a sister-in-law, so she is grateful to Minglan for her upbringing, and she is willing to be a good sister to Minglan's children.
