On that day, workers and intellectuals from all over the country gathered together. At the commemorative meeting, representatives from all walks of life made speeches. The workers put forward the requirements of "eight hours of work, eight hours of rest and eight hours of education" and shouted slogans such as "Long live the workers" and "Long live the industrial community of China".
