After lunch, I walked around the conference hall.
From 3:30 PM, I gave a 30-min invited talk. I think I did it OK, but there were not so many questions.
After the conference, I walked around the COEX mall. I did not buy anything. I will buy souvenirs at the airport tomorrow.
Banquet started at 6:30 PM.
Since I knew nobody, I picked some foods and went back to the hotel.
Tomorrow morning, I am leaving early for Japan.
