I had invited Jeff to tour South Korea with me, but he had different plans. He is good friends with Evan and Megan, and so we visited them in Taipei for a week. They were great hosts, and made the trip very easy, which was great after Korea where I was struggling to figure everything out for myself.
Before I started my research in Beijing I made two weeks of holiday in South Korea and Taiwan. In case you are planning on going to Korea, plan ahead. I was writing exams two days before I left so I ignored it, and then I wasn't able to schedule a DMZ tour or a visit to the massive shipyards of Samsung or Hyundai Heavy Industries.
