During festivals, you should bring gifts to visit your girlfriend's parents to leave a good impression on your future parents-in-law. It is also very important to give your parents-in-law a gift that pleases them.
The gift should not be too exaggerated or too shabby. People of my parents' generation don't like flashy things, so it should be practical. But after all, the son-in-law has to give face to his parents-in-law when he comes to their house, so he naturally has to spend some time to choose it, and it can't be too low-end.
First of all, you should consider that it is most appropriate to give rice dumplings during the Dragon Boat Festival. You can buy a box of rice dumplings with good taste and exquisite workmanship. In addition, you can bring a gift to each of your parents-in-law, choosing according to the hobbies and needs of the elderly. You can give good wine or good tea. You can buy a set of clothes for your mother-in-law, which is practical and face-saving.
In addition, you can also consider health aspects and give some nutritional supplements or health massage equipment, which will let the elderly fully see your understanding and thoughtfulness.
