Assembly election. In 1979, the same year which the US ceased its recognition of the Republic of China, conflict between authorities and the tangwai again turned violent in the Kaohsiung Incident. The writers of a political publication called Formosa Magazine or Mei-li-tao planned a series of political marches, first in the southern city of Kaohsiung and later a larger one in Taipei, although the Taipei rally ended up not occurring due to the arrest of the magazine's leaders.
