How about getting your dad a Chinese calligraphy set? This would allow him to practice and learn the art of calligraphy, which is an integral part of Chinese culture. Additionally, you could also get him a book on Chinese poetry or literature, or even a Chinese tea set so he can enjoy traditional Chinese tea. Another idea is to take him to a Chinese cultural festival or event where he can immerse himself in the culture and meet others who share his interests.
Or you can get him a star map with the date when he was born.
