Giving gifts to elders doesn't need to be expensive, it's mainly about the thought. The best gifts are those that show your sincerity. Some natural supplements and health products are good. If it were me, I would give my girlfriend's parents natural supplements, such as honey, sea cucumber, etc.
Or you can give gifts according to the living habits and hobbies of your girlfriend's parents. For example, if her father likes to drink, it is most appropriate to give him good wine; for example, if he smokes, buy him a few packs of good cigarettes. Such gifts can be affirmed by the elders and will not waste money. After all, it is his hobby! ! !
And for your girlfriend's mother, you can buy some high-end cosmetics or natural skin care products. Women, no matter how old they are, love beauty. Giving such gifts will definitely make her like you more.
Finally, you can consider giving some gifts with commemorative value or appreciation space, such as jade bracelets, porcelain, calligraphy and painting ornaments, etc. Such gifts can be preserved forever, are also liked by middle-aged and elderly people, and have good appreciation space. It is a very good choice.
