I've recently visited Taipei last month, for 3 days. Based on Ximending, I could visit 高記, Old Palace Museum, 蔣公 Memorial place, Longshan Temple(sad that I didn't know how to work 擲筊 back then), and many more. I felt that maybe the pinnacle of modern Chinese culture was there, then. Hope I could visit there again, very soon(my EasyCard still has 15.37TWD in it).
