Complex life experiences provide rich creative materials for writers. His first novel, Black Docker (1956), was based on his experience as a docker in Marseille.

This is a very thoughtful and artistic work, and it is a famous work of the writer.
1960 The novel Children of God is regarded as the representative work of the writer. This is a novel reflecting the strike of railway workers. The writer puts the modern struggle mode of workers' strike under the background of national liberation movement, describes it with great colors, endows it with anti-colonial nature, shows the awakening of the African working class and the vigorous development of the workers' movement, and shapes the typical workers who consciously struggle. This is a pioneering work in the history of black African literature and has had a far-reaching impact. This novel has also made great achievements in art. Like a magnificent historical picture, it not only depicts many characters belonging to different classes and strata, but also depicts the psychological activities and great changes of all kinds of characters in bright colors, thus showing the tortuous and complicated transformation and development process of African blacks from slaves to soldiers.
If "Motherland, My Lovely People" is mainly about farmers and "Children of God" is mainly about workers, then the novel "Referendum" published by 1964 is the first time to create the image of an intellectual who tries to dedicate his knowledge and talents to the cause of national liberation. This is a novel with the theme of 1958 referendum. This referendum marks that the people have been able to control their own destiny and the colonial system has begun to collapse.
