National Day is a national holiday, but for many old revolutionary people, it is also their holiday. It is indeed a holiday they exchanged their lives for. Giving a gift is also a respect. Here are some suggestions for you:
First, you can give him a National Day gift, such as a National Day commemorative coin, or a set of commemorative stamps, or a collection of great men. They must be good.
Second, if you want to give an old man a gift, you can give him some health care products or some health instruments, which is also a concern for his body.
Third, give him a creative gift. You can make a real-life doll of him as a National Day gift. Make it look like the soldier he was in those days, young and heroic. It will definitely remind him of those glorious years. He will definitely like such a gift. There are many other small gifts. Take a look. There must be a gift you like.
