Where are the calligraphers from in Li Jiayin?

Calligraphers in Li Jiayin don't come from anywhere. Because Li Jiayin (1922-1953), male, was born in Lihe, Zhao He Xia, Hong 'an County, Huanggang City, Hubei Province. 1949 participated in the revolution and was a volunteer soldier before his death. 1953 died, not a calligrapher. And Li Jiayin, male, Han nationality, native of Xingguo, Jiangxi Province, born in May 1955, with a bachelor's degree, has been working in the finance department of Jiangxi Prison Administration since 1979, and has no calligrapher's title. So calligraphers in Li Jiayin don't come from anywhere.
