Is it cheap for Liu An's boyfriend to give a gift for one day?

This is not normal. In Lu 'an, the gift money can't be less than 600 (fortunately, the money won't be used by the woman then), and the banquet that receives the woman here is also for the man. Actually, it depends on how your family understands it. Getting married actually doesn't cost much. Why save that little money? Getting married is a happy thing. Avoid these and make everyone happy!
