Is there anything particular about choosing cakes for the elderly on their birthdays?

When I was a child, I clamored to go back to my hometown in winter and summer vacations. I can not only climb trees, but also eat the most delicious food. In the evening, I can watch the stars and listen to the most amazing stories. When we grow up, we are farther and farther away from them, and they are getting older and older. I have always cared about them. So going home often is the fundamental problem, but the style of the cake can be made according to the preferences of the elderly. For example, my grandfather likes playing mahjong. You can make some mahjong on the cake to let the old man know what you still remember.
