I think it's best to do what you want, and don't use "special skills" to remind each other that you are a foreigner.

Ask your boyfriend what his parents like and give them to their parents separately. This is the best and most thoughtful way. Moreover, such gifts can be bought locally, and you don't have to go far.

If there are other elders in the family that day, such as his grandparents, be sure to find out. Some old people can't wait to see their daughter-in-law. If they don't buy presents for their elders, their parents will be embarrassed.

Most importantly, on this big day, you must dress up clean and dignified. Don't wear heavy makeup and thick soles, and wear sexy clothes. Parents in Ningbo hate this kind of daughter.
