What does it mean to be a sister in a network language society?

1. What does my social sister mean? It refers to Zhang Shuili, a seven-year-old left-behind family, who subdued a little girl who rebelled against urban teenagers in Deformation Meter, so she was called "my social sister" by netizens.

2. This word first came from a joke on the Internet called "This may be the funniest hero in the history of Metamorphosis". Disliked by rural girls, collapsed and cried. . . The video "People are getting better, but crazy" became popular online, and "Society is my beautiful sister" became popular online. The complete sentence pattern is "society is my beautiful sister, and people are cold and wild".

3. During the broadcast of Deformation Meter, Chen Xinying, a "city hero", was sent to a left-behind family in Xiangxi, Hunan Province to communicate with Zhang Fuchun, a left-behind child aged 10. However, Zhang Fuchun's family also has a seven-year-old sister, Zhang Shuili, who has become arrogant and willful, leaving Chen Xinying helpless. In the program, my sister staged a series of actions that failed to live up to expectations, such as running away and crying, spitting noodles, etc., which made the city hero Chen Xinying at a loss and on the verge of collapse. She could only spit in front of the program group and finally gave up, calling her sister "Sister Li". The strength overwhelmed the rebellious urban teenagers, so they were called "my social beauty sister" by netizens.
