1. Buy grandpa a walkman commonly used by the elderly. Simple operation. Generally, the place where this thing is sold will help you download songs, music and cross talk that old people like to listen to, and relieve your grandfather's boredom;

2. If your grandfather's physical fitness allows, you can help him buy a CD of aerobics or something similar, called rejuvenation aerobics, which is slow but beneficial to the elderly's fitness and can be done at home;

My grandfather likes collecting tickets, so we will give him our travel tickets and the tickets of colleagues and friends so that he can concentrate on his work!

In addition, you should know your grandfather's hobbies, so that you can really find a solution.

I wish your grandfather a long life, and you are also a filial person!
