In the 1990s, the family planning policy was still very tight. Many families have only one child, and many couples envy having two children at home. Whoever has twins is the envy of the people around him.

Rui Rui and Feng Feng are twins. When they are born, they have family planning. After discussion, parents think that girls can take care of boys. So, the girl Rui Rui became her elder sister and the boy Fengfeng became her younger brother. This artificially created "sister-brother" relationship is unfair from the beginning.

At home, my brother can get preferential treatment for everything, while my sister must humble herself and take care of him. Brother must play as he wants, or she won't understand. Fengfeng wanted to play chess, but Rui Rui patiently played with him. Fengfeng didn't play chess according to the rules, and her sister was patient again and again, but Fengfeng cheated again and again. In a rage, her sister stopped playing.

The younger brother seems to be on the same side as his mother. He hit his sister and told her not to talk about her, while her mother blurted out "What a nuisance", and her father's reaction was to ask Rui Rui to apologize to her mother on the grounds that "Dad finally came back for dinner, and as a result, you made him a good boy."

Unable to realize my thoughts, I finally cried out of breath and apologized to my mother, who gave me a perfunctory hug. Parents think that she knows she is wrong, but ignores that her sister needs to be recognized and respected. It is naturally difficult for an elder sister who grew up under such pressure to have deep feelings for her brother.

The significance of this documentary:

Although the documentary "Sister" is not long, it still makes people feel deeply. "Give the eldest to the youngest" seems to be the established rule in most family relationships in China, and many girls are kidnapped by "affection". After watching this documentary, I can finally understand Enron's choice for her sister.
