The most festive day in the family is the birthday, besides the wedding. An old man in the family is like a treasure. The health and longevity of the old man is what the younger generation cares most about. The birthday must be lively and lively. It is even more rare for two old people to celebrate their birthdays together, so it is also appropriate to give a gift. As for what to give, I can give you some suggestions:
1. If grandma and grandma celebrate their birthdays together, the gifts cannot be biased, and must be fair. So you can give them each a pair of "longevity" characters, and the blessing is priceless. I believe they will like it very much.
2. Of course, you can also give them each a big birthday peach, or a dragon head crutch, which means birthday star, which is also very good.
3. Of course, if it is not easy to give, you can write a birthday speech yourself, and recite it in public at the banquet. The descendants are talented, and the old people are of course the happiest.
