I believe, and stubbornly believe, that Xiaowan left this world with a smile. When your fantasy is strong enough, you can live in it.
I don't know if Mao Bijiang was moved by Xiaowan's tenderness and behavior in his last days. But this doesn't seem to be important anymore. Maybe during the relationship, Mao Bijiang had always looked at Xiaowan condescendingly, but he didn't know that he was actually just her carrier. She used him to weave gorgeous dreams for herself, and she has been living in her own world. She doesn't belong to him. She stubbornly believed in her own happiness. She is her slave girl, but she lives in her own world. Happy, like a butterfly flying over the flowers.
Yes, if we can make ourselves believe that we are happy, then why should we know the truth and reality?
Happiness is just our feeling. Xiaowan would definitely say this with a smile after she was exhausted after marrying into the Mao family.
