Hanchao.com South Korea map: .konest.com/

This map is very convenient. You can input in Chinese and query the corresponding Korean, but there is no mobile client. The navigation routes only include taxis and subways, but there are no buses. Taxi prices are not very accurate. After registering a username, you can use the favorites function. Search for the place you want to go to, and then add it to your favorites. When viewing your favorites, you can display the relative positions of all places on the page based on the distance of the attractions, making it easy to plan your itinerary.
