From characters experience's point of view, how does money change the relationship between people?

First of all, Lao Gaoman and his daughter

He used to be a flour mill, but because he didn't know how to express love, he only gave his daughter material care, even didn't know how to educate her, and only took what he wanted, so in the end there was only money between father and daughter, and money changed the expression of love.

Rasty Nie

He used to be a young man with ideals, but after the education of Fu Tuoling, Mrs. Bao Shixiong and Lao Gaoman, he clearly realized the importance of money. Money is everything and life, so he decided to wipe his conscience and climb up by hook or by crook. The tears he shed after the death of Lao Gaoman can be said to be the last tear of sympathy. From then on, he no longer cared about anyone, but made up his mind to climb up.

This is just an overview, I hope it is useful.
