He used a general anaesthetic combining wine with a herbal concoction called mafeisan (麻沸散; literally "cannabis boil powder"). Besides being respected for his expertise in surgery and anaesthesia, Hua Tuo was famous for his abilities in acupuncture, moxibustion, herbal medicine and medical Daoyin exercises.
JiaozhiJiaozhi (standard Chinese, pinyin: Jiāozhǐ), or Giao Chỉ, was a historical region ruled by various Chinese dynasties, corresponding to present-day northern Vietnam. The kingdom of Nanyue (204–111 BC) set up the Jiaozhi Commandery (; Quận Giao Chỉ, chữ Hán: 郡交趾) an administrative division centered in the Red River Delta that existed through Vietnam's first and second periods of Chinese rule. During the Han dynasty, the commandery was part of a province of the same name (later renamed to Jiaozhou) that covered modern-day northern and central Vietnam as well as Guangdong and Guangxi in southern China.
South-pointing chariotThe south-pointing chariot (or carriage) was an ancient Chinese two-wheeled vehicle that carried a movable pointer to indicate the south, no matter how the chariot turned. Usually, the pointer took the form of a doll or figure with an outstretched arm. The chariot was supposedly used as a compass for navigation and may also have had other purposes. The ancient Chinese invented a mobile-like armored cart in the 5th century BC called the Dongwu Che (). It was used for the purpose of protecting warriors on the battlefield.
Universal history (genre)A universal history is a work aiming at the presentation of a history of all of mankind as a whole. Universal historians try to identify connections and patterns among individual historical events and phenomena, making them part of a general narrative. A universal chronicle or world chronicle typically traces history from the beginning of written information about the past up to the present. Therefore, any work classed as such purportedly attempts to embrace the events of all times and nations in so far as scientific treatment of them is possible.
