Taipei International Airport looked as if it had been a major airport in Japan. Signs looked almost as same as those in a Japanese airport, except that they were written in traditional Chinese characters.
If you go to the bus stop on the first floor of the airport you can catch a route 705 bus to HSR Taoyuan Station, costing just NT$30 (almost 1USD). It’s too cheap!
There were no other passengers but me in the big double-decked bus.
