Abstract:The great February 7th Struggle broke out a hundred years ago, and it was a major event in the first nationwide wave of workers' movements led by the Communist Party of China (CPC). This great struggle forged the spirit of the indomitable struggle of February 7th, and the seeds of this spirit were accumulated through cruel class oppression. The slogans of fi ghting for freedom and human rights ignited the fl ames of this spirit. The spirit of the indomitable struggle of February 7th inherits and promotes the great founding spirit of the Party since it originated from the great founding spirit of the Party and is the practice and extension of the great founding spirit of the Party, promoting the inheritance and development of the Party's spiritual lineage. To continue to inherit and promote the spirit of the indomitable struggle of February 7th in the new era, we need to adhere to the Party's leadership in the workers' movement on the new journey, arm ourselves with the Party's ideology and theory, adhere to the correct direction of struggle, enhance our fi ghting ability, adhere to innovation and development, and rely on tenacious struggle to open up new horizons for the development of the workers' movement.
