How about a personalized calligraphy kit?
You could put together a kit that includes a calligraphy pen, ink, brush and practice paper, and have his name or initials written in Chinese calligraphy.
You could also include a book on the history of Chinese calligraphy or a Chinese calligraphy workshop. Another idea is to take him out to a Chinese cultural event, like a dragon dance performance or a Chinese new year celebration.
Or you can get him a star map with the date of your first kiss.
