If you are thinking about visiting Taiwan and you only have a few days, I want to suggest three really cool places to visit.

The first place is Hualien. I think you should visit Hualien Emerald Valley because it is hidden in the secret place in the mountains of Xiushui Township, Hualien and there is an ancient road 200 meters long. My favorite thing to do here is listen to the sound of waterfalls and feel the breath of nature.

The second place is jiufen old street. I think you should visit this place because it is Many beautiful Chinese traditional architecture attractions and There are many vendors selling local famous products and traditional local food.My favorite thing to do here is enjoy the beautiful scenery of Jiufen while eating food on a beautiful night.

Finally, I also highly recommend that you check out High heel church. I think you should visit National Palace Museum because it is a symbol of Chinese culture and history and meaning of education. My favorite thing to do here is see beautiful and precious historical relics.
In closing: if you visit Taiwan, remember to visit Hualien Emerald Valley, jiufen old street and National Palace Museum. They are great places to visit.
