How much bride price does Gao Qing need to get married?

How much do parents usually give? I asked my colleagues, classmates and relatives around me that when they got engaged, the gift money ranged from 10 thousand to 30 thousand. My boyfriend said that he had never heard of giving gifts when he got engaged. How do you say this? And he heard that the man's ring was bought by the woman. Is that so? I'm from Tangqiao.
