Ensure Korean hanbok does not include architecture and costumes from China or Japan

Thank you for your detailed feedback. I do not know enough about these styles to know what is correct or not, so in this case I cannot do testing.

Since Adobe Firefly is trained primarily from the images in Adobe Stock, it might be worth looking at Adobe Stock images and see what it might have that is Korean versus Chinese or Japanese.  It is possible it does not have sufficient training data from Korea, so it is pulling from Chinese and Japanese imagery. 

It is also possible that it might not know what region you are looking for, even if you are writing prompts in the Korean language. Are you specifically saying "Korean" in your prompt? When the same word can apply to different cultures differently, you might need to be more specific on region/location/culture in your prompt.

Finally, when you encounter images with mistakes as you describe, please mark them "thumbs down 👎" and then click on feedback and leave more detailed comments on what is wrong.

I usually also click "other" and fill in details on exactly what was wrong in the additional box.
