What is the relationship between Zeng Guofan and Gu Weijun?

It's okay. Zeng Guofan was a politician, strategist, philosopher, writer, calligrapher, founder and commander-in-chief of Xiang Army in the late Qing Dynasty. Gu Weijun, whose name is Shaochuan, is one of the most outstanding diplomats in China's modern history. He was the 13th head of the Beiyang government, and served as the chief foreign minister of Beiyang government, the ambassador of the national government to France and Britain, the chief representative to the United Nations, the ambassador to the United States, and the vice president of The Hague International Court of Justice. There is no direct relationship between the two.
