What should college students do when they travel to Korea alone?

There are two ways to travel to Korea. If you have a Korean tourist visa, you will go to more places. The whole of Korea can go. Including Seoul. It should be more convenient for you to apply for multiple visas to Korea in Beijing for five years. Specific details and regulations can be understood by visa agencies. If you don't have a visa, you can only go to Jeju Island, because it is a visa-free place. About the schedule. For scenic spot planning, route design, accommodation reservation and flights, you can learn more about and make reservations in official website or Ctrip in the Spring and Autumn Period. Whether you have a tourist visa or not, you should book round-trip air tickets and hotel accommodation before leaving for Korea, because Korean immigration officials need you to show your flight and accommodation information. South Korea's social laws and regulations are relatively perfect, social security is also good, the city is clean and tidy, and the quality of citizens is OK. It's convenient to transfer to J Seoul subway, and public transportation in other cities is also good. The consumption level is slightly higher than that of Shanghai. Because of time, I won't explain it in detail.
