After the smashing of the “gang of four,” he first set off a challenge to “two things ” and triggered a major discussion on the issue of the standard of truth. At the critical juncture in the face of the pressures of high-level discussion, he first uttered his voice and took a clear-cut stand. To support practice is testing the truth and reversing the unfavorable situation of ideological emancipation. In the northeast talk, he started to fire and boosted the discussions on the criteria of truth to form a prairie fire that eventually defeated “all ”, Clearing the ideological barrier for the reform and opening up.
