On April 27, 1911 (March 29 on the lunar calendar), the United League known as Tongmenhui launched an uprising in Guangzhou as part of the revolution to overthrow the Qing dynasty and set up the Republic of China.
Sun Yat-sen led the failed uprising, with 70 bodies buried in Huanghua Gang.
But later it was found that 86 martyrs were killed, including 30 overseas Chinese.
Soon after the success of the revolution, the Nationalist - or Kuomintang - government decided to build a cemetery for the martyrs and it was finished in 1921.
Activities to commemorate the uprising are always held on March 29.
