Personally, I like Lin Daiyu best in the whole Dream of Red Mansions. First of all, her appearance is outstanding, which is beyond doubt. Cao Xueqin described her appearance from many angles, and in my opinion, her appearance is also in line with the current public aesthetic, thin and girlish. In addition, excellent talents are more likable. Look at her handy poems, which are beautiful and moving, which is also the main reason to attract some fans.
As for her character, there are many disputes. Many people think she is pessimistic, sensitive and aloof. These don't deny that she did, but it was after her father's death that she became so cautious. When her father was still alive, she was cheerful and lively. Think about the girl Jia likes. For example, Xiangyun is like this. After her father died, although there were still such things.
And her love for Baoyu. Many people will think that she is too petty and far less attractive than Baochai. Indeed, she will be angry with Baoyu at first, and will deliberately ignore Baochai, but after knowing everything, she will return to nature. And I think the relationship between her and Baoyu is the purest, just like we are now, so we are both suffering from loss in love.
