Don't you find the Korean subway system quite inconvenient?

Hello, we are students from the Department of Visual & Media Design at Sookmyung Women’s University.😆
We are currently developing an app to provide better services for foreigners experiencing difficulties with the Korean subway system.🚃
To achieve this, we are conducting this survey to gather thoughts and experiences from foreigners facing challenges in the Korean subway.🚇
The survey will take approximately 5-10 minutes to complete.
Among those who complete the survey, we will give a Starbucks iced Americano gift card to 5 participants. ☕️
