Introduction to London Metropolitan Police: London Police Station, Embassy of the Qing Dynasty in the UK, Sun Yat-sen’s London Tragedy Site and other attractions reproduce the history of Dr. Sun Yat-sen’s martyrdom in the UK. After escaping from danger, Dr. Sun Yat-sen wrote “The London Tragedy” in English. This book was later translated into Chinese, Japanese, Russian and other languages, which expanded the international influence of the revolutionaries.
