Philosophy of Relationship Marketing

A shy boy studied by himself in the classroom and saw a girl he liked very much. Seeing that the girl was leaving after reading the book, the shy boy blushed and chucked up a conversation in front of her face: can you lend me 10 yuan for noodles? I lost my wallet in the dormitory. Here is my student ID card. Please give me your cell phone number and I will pay you back later. The girl thought for a while and said: OK. When he was paying for it, the boy said again: if you can borrow 20, I will treat you to have a bowl too.
The core of Relationship Marketing is to gain the trust of the other party first, and achieve its ultimate goal in the way of gradient promotion!
