taipei times: Painting of KMT emblems ‘inappropriate,’ Hau says

Taipei Mayor Hau Lung-bin (郝龍斌) yesterday ... said the four gates were national monuments and that the city government was authorized by the CCA to maintain the gates.
“It is inappropriate to paint the KMT emblems on the four gates if the patterns were not there originally,” he said.

... Department of Cultural Affairs Commissioner Lee Yong-ping (李永萍) said the KMT emblems were first painted in 1955 when the KMT modified gates left over from the Qing Dynasty.

...“We are simply restoring the four gates and making the monuments the way they were in 1966. The KMT emblems were on the gates, and so it is natural for us to repaint them,” said Lee, who is also a KMT member.
