Wu Jushan's integrity, behavior and careless handwriting are extremely clever. "Jiangning Fu Zhi" records that "Yuan Liu Jian Kang is near the east building of the city, with a couch at the end of Wei Dynasty, loving beauty, and being with Wang Tie." He doesn't have many hobbies, often entertains himself in ancient posts, and is known to Xiaozong for his outstanding words. His books, such as Mi Fei, are exquisite in Xiangyang, and have the style of "flying with pride and muscular". However, due to Wu Ju's great imitation of Mi Fei, Wu Ju's calligraphy lacks originality and artistic personality is not obvious.
