Who is Gao's disciple?

Gao's apprentice has only four apprentices, namely, Wan Jing, Wu Zhanao and Jin Qingbei. The reason why Gao adopted Zheng Zhi's method is because of the relationship. There are only four disciples in the history of Zheng Zhi, namely Zhang Zaixin, Wan Jing, Wu Zhanao and Jin Qingbei. A five-character official script couplet collected in Qingdao Museum today was written by Zheng Zhi to Zhang Zaixin's father Zhang zhen, and his Collection was also inscribed by Zheng Zhi. When Zhang zhen was in imperial academy, he went south to Jiangsu and Zhejiang and visited Zheng Zhi in Nanjing. She especially praised his official script, saying that the study of six books has not been talked about in the world for a long time. I went to Baixia and found that I could be a servant, but Jun Zheng Taniguchi won the China Family Law. Perhaps out of admiration for Zheng Zhi's calligraphy, Zhang zhen ordered his son to learn calligraphy from him.
