He Xiu,a Gongyang scholar,made a lot of analysis on the principles of recording the date and month and time from the perspective of detailed and brief.Based on the thinking of binary opposition,He Xiu treated the three elements of day,month and time in two,that is,the day and month are relative,the day is detailed and the month is brief;Month and hour are relative,month is detailed and hour is omit-ted.He Xiu explained the general meaning of praise and criticism from the detailed and strategic impor-tance of the sun and moon,but he did not adopt the thinking of binary opposition to clarify the praise and criticism,that is,it is not a detailed record of the day and month to show commendation,but a brief book means derogation;In fact,the details of the day and month show the depth of praise and criticism.It is precisely because the details of the day and month have the changing relationship of depth and weight in the interpretation of meaning,so it is easy to be combined with its third evolution theory,so it is endowed with the significance of kingly evolution.With the evolution of the third generation and the gradual realiza-tion of kingcraft,the differences between the weight of the day and month gradually disappeared,thus completing its mission of kingcraft evolution.
