What happened to Zuo's descendants after his death?

The eldest son: Zuo (1846- 1873), with heavy words, won the care of the left, and was mainly shaded. After he settled in Xinjiang, he went to visit relatives in the army. When I was admitted to the army account with my father, I got sick with a cold. When I get home, I can't afford to get sick. I'll say "filial piety" after I die.

The second son: Zuo Xiaokuan (born in 1847), a doctor, whose cause of death is unknown; The third son: Zuo Xiaoxun (born in 1853), director of the Ministry of War, whose cause of death is unknown; The fourth son: Zuo Xiaotang (1857- 1924), with different words, was proposed by Jiangsu, and the cause of death was unknown.

Among Zuo's sons, only the fourth filial piety is a high official in the army. During the Sino-Japanese War of 1894-1895, Wu Dayou, a former governor of Hunan Province, commanded the army on the Liaoning border, with Zuo Xiaotong as the general manager. After the war, Zuo Xiaotong retired to his hometown to live in seclusion until his death (thus, the officialdom was warm and cold). Zuo Xiaotong is good at writing Xiao Zhuan and can spread his father's teachings.
