Why doesn't Furong let Bixi grow flowers and plants in Huang Zhenyi?

Didn't you read it? Because tourmaline longevity asked the lotus what head to wrap (reward) when undressing it.

Furong asked him about the future of female music. Then tourmaline longevity didn't give her a plate, and tourmaline longevity said to Furong

He still has endurance to deal with women who love money, but he is not interested in women who have the same power. And that bad old man is Furong's punishment for exposing his thoughts! This is also her last chance. If not, she cannot become a geisha.
