Can I use lowercase Ling Fei Jing in the calligraphy competition?

The small print in Beijing can be used in the competition.

Known as the world's first lower case, Ling Fei Jing itself is a Taoist classic. It was written in ink during the Kaiyuan period of the Tang Dynasty. It is beautiful and vivid, and it is a masterpiece of Jing. As a small calligraphy post, it has nourished generations of calligraphers. The works participating in the calligraphy competition should be healthy and uplifting, and the writing content must be selected from China's classical poems, and the sentence meaning should be kept intact, so the Ling Fei Classic can be used.
