General situation of Gangu calligraphy art

I know that there are calligraphers in Gangu: Jin San (Wang Jinshun), Wu (Yu An), Wu Tie (Li Guo), Jiang Xiaoniu and so on. Li Guo knows himself very well. He is a second lieutenant officer of the former Kuomintang Xi 'an cavalry school. He once taught Mandarin in Gangu No.4 Middle School. He is generous, addicted to gambling and has the usual hobbies of young people. I lost the election because of my Kuomintang status. Good at cursive writing.
