I suggest you:
As long as you search for "Gongbi Peony" on the Internet, you will get a lot of pictures and materials.
Then you can use the inscription of "thin gold book font" yourself.
As for the content, any song will do.
Like don. Xu ning? ：
Who doesn't love peony flowers,
Occupy the good things in the city.
Suspected goddess Luoyang,
Break the morning glow in various ways.
In my opinion, this is a very good song to celebrate the Millennium Peony Festival.
