I was very exciting when I boarded the flight for Taiwan. The plane flew for about four hours after it landed on the island. On arrival, we were greeted by local guide. We stayed in Taiwan for eight day. During our stay, we went boating in Riyuetan Pool, that is a beautiful lake. We visited Mountain Ali, where we went hiking.
