If a son's girlfriend comes home in the name of meeting the parents formally, if the parents have a good impression of their son's girlfriend, they should give a red envelope during the first visit. The amount of the red envelope should be determined based on local customs and the degree of favorability towards the son and girlfriend, and more importantly, it should make the woman feel the importance that the man's parents attach to her.
Of course, when leaving, if the parents have a good impression of the girl, they need to give her a red envelope as a gift and express the feelings of the groom's parents. If it is a serious meeting, you can package some lucky red envelopes with numerical values, such as 888 yuan (meaning: send, send), 999 yuan (meaning: long stay), 1001 yuan (meaning: choose one from a thousand miles), etc., which are all very suitable.
However, some girls may refuse red envelopes, and there are also cases where the amount given is a gesture of politeness from the man's family. Whether or not a girl accepts it is a sign of politeness. As long as we treat our son and girlfriend with sincerity, enthusiasm, and sincerity, I believe she will definitely feel the parents' care.
