To round out this re-evaluation, Luo Siding put forward a new interpretation of the precipitous collapse of the Qin Dynasty in an article entitled "On the Class Struggle During the Period Between Qin and Han" in a 1974 issue of "Red Flag", to replace the old explanation. The new theory claimed that the cause of the fall of Qin lay in the lack of thoroughness of Qin Shi Huang's "dictatorship over the reactionaries, even to the extent of permitting them to worm their way into organs of political authority and usurp important posts."
