But,
it was impossible for her to stop searching for him. Sister Bing, after all, was a very distinctive and independent woman, or you could say she was stubborn and unreasonable.
After searching for him for so many years without a single piece of news, asking her to suddenly give up the search... She definitely couldn't do it.
So,
I think that Sister Bing's persistence in searching for Cai Zhihua was not because she still loved him deeply but because she had to find him.
If she couldn't find him, she would keep searching her whole life, always hiding her affection for you, and even though she might spend her whole life by your side, she'd never be able to be your woman.
If she found him, her emotional entanglements would be resolved, truly resolved. Just now, upon hearing news of Cai Zhihua, she wasn't excited nor angry,
That is the only explanation!
Grandpa,
Let me put it in a metaphor.
