1. If you just want to have a family dinner for 2-3 tables, you can sit according to your generation, such as sitting at a table with your grandparents, sitting at a table with your fathers, and sitting at a table with your juniors. In this way, the old people are also very happy to see it.

2. Make a big cake, preferably representing longevity, and take it out to sing a birthday song when eating or after eating;

3. Everyone gives his grandfather a gift to express his own mind, which can be self-made, because what the old people value now is not money, but your mind, which can be sent by the whole family;

Finally, in fact, anything can be done as long as the old people are happy. Don't you think so? I hope I can help you.
