This question is a bit difficult to say. There are several customs in Lu 'an, which may be different across the street. I'll tell you simply, if your girlfriend really likes you and has no gift, just give her 999. Still not giving it to her. Oh, but you must have a gold ring. What kind of gold depends on how you and your girlfriend decide. On the day of engagement, you should bring the matchmaker and two boxes of white wine, two boxes of red wine and four cigarettes to the woman's house to meet people, and then go to the restaurant to eat and chat ~ ~! My hometown dialect will be fine.
