Self-guided travel to Taiwan, please ask: 1. Can I buy things directly in RMB in Taiwan? If not, how much is it to convert RMB into Taiwan Dollar? 2. Go to Guishan Island in Yilan. The pictures are beautiful, but what is the actual situation? If you have a one-day itinerary, where should you go by car, train or Shinkansen, and how much is the fare? It would be best if you can recommend some delicious food and scenic spots in Yilan, I would be very grateful. Thank you my dear friends. grateful.
