Spent a lot time in Tianan. Was very nice. Now I am in Suzhou, China. I liked Taiwan MUCH MUCH better. You can even sneak off to the mountains or the beach in a day trip!
Also, it is more congested in Taiwan than China so even more scooters. Spent a lot of time in Tianan at the red wolf. Also, the people are Chinese but think more freely, like Americans.
Good Luck!
