I wrote a calligraphy work of Yueyang Tower, which is an excerpt. The title only wrote the words Yueyang Tower, not Fan Zhongyan, and did not indicate that it was an excerpt.

The content of calligraphy works is generally not so strict. What you want is good handwriting and good composition. You wrote Yueyang Lu Ji instead of Fan Zhongyan, which is no problem at all. I don't think it is a big problem not to write excerpts. If the selection criteria are not so strict, it may not be a problem at all. You can read the specific requirements of the competition carefully. Good luck!
