Jeong In-seong Internal Medicine Clinic in Gangdong-gu urgently needs to introduce a reservation system.

I rushed there early in the morning and waited before they opened to be the first to enter, but I think I still waited for almost an hour. If I could make an appointment, I wouldn't have to waste hours waiting every time, drag my aching body in the cold, and suffer; that is always a bit of a shame. Still, since today was a general routine checkup and I had to undergo five tests, I expected it to take a long time. However, since I was the first one there and got tested first, it finished earlier than I thought, which was nice. Going to the 3rd floor and moving back and forth for the tests was short and simple, so I think I managed to get through it without any difficulty. The nurses were also kind and helpful. Aside from the over an hour I waited, the actual testing took less than 30 minutes.
