1. First of all, I suggest you send a massage gift. Such as massage cushion, massager, foot bath tub, etc. Dad's biological age is the most suitable gift.

2. You can give Dad a practical gift. Such as watches, belts, wallets and other gifts.

3. If you know dad's preferences and sizes. You can buy some clothes, shoes and other gifts.

4, you can also send some magnetic therapy, mahogany jewelry. Very suitable for the elderly.

5. Look at dad's special hobbies, just choose a gift according to dad's hobbies.

That's about it. You should choose a gift according to your specific situation. I hope the above suggestions are helpful to you:)
