This sentence came from a fable written by the Tang Dynasty poet Zhang Ji in the "Shi Shuo Xin Yu Rong Zhi". It was about a beautiful woman who died of loneliness because of her independence and arrogance. The woman in the story was called Flying Sparrow Zhao. She was a dance genius who was praised for her beautiful dance moves and unique temperament. However, she had a proud personality and refused to associate with other women. She also did not like to share her privacy with others. This personality eventually led to her loneliness. The meaning of this sentence was that in real life, some people were unwilling to share their resources and advantages with others because of their pride and independence, which eventually led to their helplessness and loneliness. Therefore, we must learn to communicate, cooperate, and share with others to maintain our competitiveness and attractiveness.
