This is a growth account with no golden words and lack of "nutrition".
The full text records the conversation between Liu Sangsang and her friends from youth (respectfully called the fat pig period) to mature (bushi). If you think she talks a lot and has a lot of inner drama - congratulations, your perception is absolutely correct.
The author has searched the whole article and really can't find any profound ideas. Its only advantage may be that it has many words.
Intention: The journal record is not a "sharp change" for Liu Sangsang, but a "flow".
