Zhuge Liang was Chancellor of Shu Han during the Three Kingdoms period of China. He is often recognized as the greatest and most accomplished strategist of his era.  Often depicted wearing a robe and holding a fan made of crane feathers, Zhuge was not only an important military strategist and statesman; he was also an accomplished scholar and inventor. His reputation as an intelligent and learned scholar grew even while he was living in relative seclusion, earning him the nickname "Wòlóng" (臥龍, or "Sleeping Dragon").  Zhuge is an uncommon two-character compound family name. His name – even his surname alone – has become synonymous with intelligence and tactics in Chinese culture.
