Daiyu used poems to express her feelings of parting. She writes mostly sad poems, and often thinks of death, old age, dispersion and decline. The author believes that it is precisely because of Daiyu's weak body that she reacts negatively to things, and everything is considered from its negative side, which also leads to Daiyu's extremely passive way of thinking. A person's temperament is linked with personality. A certain temperament is more likely to form a certain character. For example, a sanguine person is likely to form a helpful and lively character, while Daiyu is depressed, which lays the foundation for her character formation? Function, so that she "likes to leave without gathering" and "likes to be quiet without moving". The daughters of the Grand View Garden all know that she was born with such temperament, and they don't have too many demands on her. These sisters prefer Baochai to Daiyu. Every time Xiangyun comes to Jiafu, she always likes to look for Baochai instead of Sister Lin, which gradually reduces Daiyu's social interaction with others and encourages her melancholy personality. The influence of family decline on Daiyu is that she dares to love but dare not speak. Only by keeping her love deep in her heart, expecting others' help and pinning her love on others' pity, did she form a strong sense of dependence. Only by holding the straws and keeping love, as the saying goes, if you love deeply, you will be hurt deeply. Finally, until I give my life for love.
