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.
