Stations: Over 600 stations connect Seoul to its neighboring cities like Incheon and Gyeonggi-do.
Colors: Each line has a unique color (e.g., Green for Line 2, Blue for Line 4), making it easy to follow the signs even if you can't read Korean yet!

4. How to Read the Subway Map Like a Pro ๐จ
Follow the Colors: Every line is strictly color-coded. Just follow the colored strips on the floor and walls when transferring.
Check the Destination: On the platform, check the final destination of the train (e.g., "Toward Gangnam" or "Bound for Incheon") to ensure you are on the right side.
Use the Numbers: Each station has a 3-digit number (e.g., Myeong-dong is 424). Even if you can't read the name, you can follow the numbers!
