The subject was officially taboo for decades. On the anniversary of the event in 1995, President Lee Teng-hui addressed the subject publicly, a first for a Taiwanese head of state. The event is now openly discussed and February 28 is commemorated as Peace Memorial Day (traditional Chinese: 和平紀念日; simplified Chinese: 和平纪念日; pinyin: hépíng jìniànrì ), and details of the event have become the subject of government and historian investigation. Every February 28, the president of the ROC gathers with other officials to ring a commemorative bell in memory of the victims. The president bows to family members of 2/28 victims and gives each one a certificate officially exonerating the victim of any crime, who were previously blacklisted as enemies of the state. Monuments and memorial parks to the victims of 2/28 have been erected in a number of Taiwanese cities, including Kaohsiung and Taipei.[3][4] Taipei's former "Taipei New Park" was rededicated as 228 Peace Memorial Park and houses the National 228 Memorial Museum to commemorate the tragic incident, which opened on February 28, 2011.[citation needed]
