Liang Hu, a famous calligrapher of Gansu origin in the late Eastern Han dynasty, experienced three important stages in his life: In the early period, he was elected to Hongdumenxue and became eminence by his handwriting; In the middle period, he took refuge in Liu Biao to avoid chaos in Jingzhou; In the later period, he was attached to Cao Wei, writing diligently to show his loyalty. The establishment of Hongdumenxue marked the transition of academic focus from Confucian classics to Literature and Art in the late Han Dynasty，Liang Hu has thus ushered in a special opportunity to showcase his calligraphy skills. Although the turmoil in the late Han Dynasty caused unconstrained fluctuation in Liang Hu's life, it also made him continuously integrate into the new academic centers during the Han and Wei dynasties, making his calligraphy skills more exquisite and mature. His BaFen handwriting such as the Kongxian stele shows powerful momentum, representing the highest level of BaFen handwriting in the late Han Dynasty and the early Wei Dynasty. The separate naming of the BaFen genre is also closely related to the achievements and influence of Shi Yiguan and Liang Hu.
