What does the plug of skypark 1 Hotel in Seoul look like?

China's electrical appliances need this adapter when they are used in Korea, because the sockets in Korea are two round holes, and the plugs of Korean electrical appliances are two cylinders, just like the above picture, not only in a hotel, but also in all electrical appliances in Korea. If not, it needs to be used normally in Korea.

Han You. Com has a conversion plug specifically for Korea.
