孔子生平 The Biography of Confucius
(Proper nouns such as name of a person, titles, name of a book, feudal state, and places will be included as Chinese in order to keep the correct reference. A brief note to explain may be followed immediately. Since I do not have the reference book on standardized Pinyin, I have no choice but to use the phonetic either from the computer or from other sources. Confucius is the Romanization or in Latin version of 孔夫子; Con Fu Ci means Professor Con.)
Per the information in The Noble Confucius Family recorded in the History Archive (《史记·孔子世家》, a record being considered as the most authority history writing in China), Confucius was born in the era of the 22nd year of Lord Shiang, Duke of Lo (鲁襄公) but the month and the day were not identified. Per the record of Guk Liang (《谷梁传》, a book footnoted writings about Confucius), Confucius was born in the tenth month and the gang-ji day (庚子). Therefore, his birthday should be in September 8th 551 BC.
Confucius was born in Dukedom of Lo (鲁). Lo was a feudal state granted to Baak Kam (伯禽), son of Lord Dan, Duke of Jau (周公旦). Lo was known in keeping the culture and all documents of the Imperial Jau Dynasty (周朝) in good condition, and also the state practicing the righteous ritual and music（礼乐之邦）. In the era of the 29th year of Lord Shiang, Duke of Lo, i.e. 554 BC, Sir Gwai Ja, son of Earl Wu (吴公子季札), commented that ‘the music in Lo is ultimate’. In the era of the 2nd year of Lord Chiu, Duke of Lo (鲁昭公), after reading the official records of Lo during his visit, Hon Suen Ji (韩宣子), the high-ranking officer of Jun (晋) commented that ‘the righteous ritual of the Imperial Jau Dynasty is virtually in Lo’. The ideology development of Confucius was greatly influenced by the traditional culture of Lo as well as the contemporary switching of the qualification to be a scholar.
