The spring and summer
bulletin is also called the south and sorth bulletin.There are several po ints about the reason of
the event such as examiners' bias,struggles among part ies,the accidental error of the northerner and the deviation of the
enrollment.M any proofs have stated clearly:there are no enough reasons to support the first and second points;the third point is the saying of avoiding the fact;the forth point is reasonable.This event seems to be a cheating event of imperial examinat ion related with the struggles among parties.In fact,its deeper reason is a prob lem of political weighing and strife.Its purpose is to balance the confucian enl ightenment between south and north and then to balance the domination between th em.Objectively,it has the positive significance in the development of
northern c onfucianism and in promoting the renewal of the northern confucianism.At the sam e time,it also lays a foundation for successive emperors to continue this policy and to take the gentle distribution system of enrollment.
