There are quite a lot of birthday gifts for elders. Here are some suggestions for you. I hope they can inspire you:
1. Give your uncle something he likes. For example, if he likes surfing the Internet, you can give him a smart high-definition camera, or a set of unlimited keyboards and mice, as well as headphones and speakers with better sound quality; if he likes sports, you can give him some sports equipment. Anyway, you have to cater to his preferences, so that the birthday gifts you choose are what the elders like.
2. Give something more practical, such as a watch. Generally, men like to wear a good watch when they reach a certain age, which can reflect his status. If your uncle doesn't have a watch, buy him one. Or give him a pen and a tie, which are also very good. You can try it.
3. Generally, elders who don't smoke or drink will definitely like to drink tea. You can consider giving your uncle some good tea, such as Tieguanyin, Dahongpao, and Pu'er. Drinking tea is not only good for the body, but also can cultivate one's body and mind. It is a good birthday gift.
