At that time, the situation was very grave.

After the May 30 uprising and the August 1 uprising, the Japanese imperialists intensified the repressive campaign in Manchuria and destroyed many underground revolutionary organizations.

In order to save the difficult situation, the President launched efforts to unite the masses.

He organized a short course at Dunhua for members of the Korean Revolutionary Army and core members of revolutionary organizations and discussed ensuring unified leadership over basic party organizations and rallying people.

He convened a meeting of cadres of the party and the Young Communist League in Mingyuegou on May 20, Juche 20 (1931).

At the meeting he delivered a historic speech, "Let Us Repudiate the ′Left′ Adventurist Line and Follow the Revolutionary Organizational Line.  He in the speech made a profound analysis of the reactionary nature of the May 30 uprising and put forth a revolutionary organizational line on uniting the whole nation into a political force by closely rallying the basic masses and other anti-Japanese forces of all social strata around them.

After the meeting the revolutionary organizations in Mingyuegou and Antu were put on the right track in a short span of time and those in other areas revitalized.
