 While in Europe, Zhou, also named as John Knight, studied the differing approaches to resolving class conflict adopted by various European nations.In London in January 1921, Zhou witnessed a large miners' strike and wrote a series of articles for the "Yishi bao" (generally sympathetic to the miners) examining the conflict between workers and employers, and the conflict's resolution.After five weeks in London he moved to Paris, where interest in Russia's 1917 October Revolution was high.
