We arrived at Penghu, one of the outer islands of Taiwan, our first stop on the journey. Before departure, I decided whether to take a flight or a boat. After careful consideration, in order to shorten the transportation time, the boat trip took 4.5 hours. There was not much difference in price, so I finally chose UNI Air. Before departure, I had been a little worried about taking a small plane, but after seeing the actual thing, I felt more at ease. It was a short 25-minute flight and it felt good to see the blue sky and clear sea.
