The ninth day of the ninth month of the lunar calendar is the Double Ninth Festival, a traditional Chinese festival. People are used to worship their ancestors and wish the elderly at home a healthy and long life. On this day, everyone should visit the elderly at home. It is a good idea to give grandpa a gift. I can give you a few suggestions:
1. Send some fruits or nutritional supplements. It is also a kind of respect to care about the health of the elderly. Their health is what you want to see most.
2. Send a creative gift, you can send a real doll, made into a family portrait. I believe that what the elderly want to see most is family reunion and a good life. Such a gift is placed at home, and the whole family will see happy looks every day. I believe he will be very happy.
3. Send a good blessing to grandpa, you can send a calligraphy to grandpa, write the word longevity, etc. I believe that the elderly will like such a classical gift very much and will be very happy.
This is my suggestion, I hope you like it.
