8 days and 7 nights free travel in Taiwan. I don’t know if this itinerary will work. Please answer me! (There is also where to go in Taitung and Taichung if time permits)

1. Jiufen is in the northeast corner, so it can be placed between Taipei and Hualien, so that you won't walk twice. <br/>2. The eight-day free travel around Taiwan is too rushed, and too much time is spent on traffic. <br/>It is recommended to travel freely in northern Taiwan and use the high-speed rail to and from Taichung or Kaohsiung at most!

1. It’s a bit rushed to stay in Green Island for only one night. It’s better to stay for two nights<br/>2. Green Island has to go to Taichung in one day, and basically spends the whole day by car. You have to take the South Link Line, which can be considered Take the ordinary train twice a day (without air-conditioning train), it’s very tasty, just walk slowly to Pingtung or Kaohsiung, and then go to Taichung the next day
