After the Cultural Revolution, the Children's Palace resumed, and he became the first student in the calligraphy class, and immediately won the first place in the Tianjin Children's Calligraphy Competition. 1976 is an unforgettable year. Cui Hanbai was introduced by the old dean of Tianjin Academy of Fine Arts and studied under Mr. Wang Xuezhong. Later, he studied seal cutting management from Mr. Xu Yuling, a famous seal engraver in Jinmen, and Mr. Gong studied official script. From junior high school to senior high school, a large number of inscriptions have been written, among which the epitaph of Huangfu tablet, the tablet of Han Dynasty, Sun Qiusheng of Northern Wei Dynasty, Cui, You Jun's Seventeen Monuments and Preface to Bishop Wang Xizhi have far-reaching influence.
After the Cultural Revolution, competitions and exhibitions suddenly appeared, and his earlier kung fu immediately came in handy. He won the first prize in the first national college students' calligraphy competition, and entered the fourth national calligraphy and seal cutting exhibition when he participated in the national exhibition for the first time. His achievements in calligraphy far exceed those in medicine.
