Nantou Passenger National Hotel, just opposite the National Hotel, can buy a ticket to enter and exit indefinitely every day. When you come out, remember to let the staff stamp on the back of their hands. It's beautiful to take pictures on sunny days. Blue skies, green mountains and green waters. When we go, we just meet the windmill festival. There is a water dance show of fountains on the whole time. It's very nice to watch at night.
