To Comrades Lin Biao and Zhou Enlai: The stance of excluding the Jiaotong University faction and supporting the ultra-“left” camp merits careful study. We should continue our investigative work and need not rush to take a public position. As for the sabotage of factories, the ultra-“left” group is suspected, whereas the Jiaotong University faction has not engaged in such acts. Please consider accordingly.

After Enlai has read this, please forward it to Comrade Lin Biao.
