Introduction to the founding organization: On November 15, 1919, after the establishment of the Awakening Society, Zhou Enlai presided over a special meeting of the Tianjin Awakening Society. It was decided to build the Awakening Society into an "organization prepared for sacrifice and struggle", a "vanguard in guiding society" and a "base camp for combat". When deciding to recruit new members, the person should introduce himself first, and the introducer should report his advantages and disadvantages, and then the meeting will review the membership before everyone agrees to join. Gradually, the organization of the Awakening Society grew.
