Koreans don't use internet to make friends, and the chat tools they use must be information that can be found in the National Intelligence Agency before they can apply. So they usually know people they know. Unlike our QQ, anyone can apply. If you really want to learn Korean, I recommend a method for you. You can post an advertisement in the university saying that you want to meet Korean friends, leave your phone number and write it in Korean. Someone should contact you. However, it is recommended to meet same-sex friends. Even in China, Korean boys still do. . .
