20th anniversary of the 1989 Tiananmen Square protests protests of 1989, thousands of students and protests had gathered in Tiananmen square, when troops opened fire. An unknown number of people were wounded or died in the incident. As the People's Republic of China has publicly embraced the one country, two systems model of governance for Hong Kong, the annual 4 June observance which has become a tradition since 1989 has continued after the transfer of sovereignty from Britain to China. It is the only place on Chinese soil where the event is openly commemorated in any way and on any scale. The 20th anniversary was commemorated in the
1989 Tiananmen Square protests to suggest that a massacre took place on the Square itself. Records by the Tiananmen Mothers suggest that three students died in the Square the night of the Army's push into the Square. Democracy activist Wu Renhua asserted that the government's discussion of the issue was a red herring intended to absolve itself of responsibility and showcase its benevolence. Wu said that it was irrelevant whether the shooting occurred inside or outside of the Square itself, as it was still a reprehensible massacre of unarmed civilians. The authorities carried out mass arrests. Many workers were summarily tried and executed. In
