Three Problems of Granting Nobility by Military Distinction seen from Two-Year Statute

There is no record, in historical documents and bamboo slips of Qin and Han dynasties, of the matching between military rank and nobility grade, the position of women under such a system, and how the titles were inherited. Two-Year Statute preserved 20 contrasts between nobility grade and military rank and laid down the rules of inheritance. From here we can see that in the period of Empress Lu, this system had practical value and was respected in society.
