Taoyuan Airport is quite large, and the goods sold are cheaper than t3. I bought cleansing oil from Uemura Hideo, T3 sold 488, and Taoyuan sold 437. The waiter's attitude is much better than T3, so he is very warm and friendly. You can sell it in Taoyuan, and you can pass by the duty-free shop when you walk to the waiting room. There are many cosmetics besides duty-free shops. We traveled to Taiwan Province with Zhongxin and also took Taoyuan Airport.
