The 'Chronological Table by Months from Qin tο Chu' recorded major events that happened during the period from the Second Emperor of Qin (209B.C.) to the establishment of the Han Dynasty (202B.C.). Of the Ten Tables of Shiji, it is the table that covers the shortest period of time and uses the smallest unit of time. The rules governing its timing have not been correctly analyzed by any readers or historians, and have been criticized so severely that its significance and uses could not be estimated properly. By examining every case in this table, it becomes clear that there are three types of time- recording in all: 1. that using signs of the official calendar such as yuan-nian (元年)and jeng-yueh (正月);2. that using the number of months since the rise of the characters; 3.that using the number of months as well as of years. In the light of above analysis, nearly all of the rules of time- recording can be recognized, and 98% of the cases can be explained logically. With the understanding of the rules and their characters, the readers of the Table can easily find the historical changes during that eight years. In addition, the Table also includes many important and special records. In conclusion, the Table is essential to understanding what actually happened in the history of Qin and Chu that cannot be found elsewhere.
