One sees a rapid increase in languages around Seoul other than Korean and English. Here are two notable bits of signage.
One is a mobile phone store with a sign in Chinese aimed at the increasing Chinese market in Korea. I am told that Chinese students have often more disposable income than Korean students at Korean universities. Have not conducted a study yet.
The other sign is for an Indian culture event. The poster does not assume a readership of Hindi, or maybe it does. In any case, Koreans previously had no tolerance for the Hindi language. That environment is changing quite rapidly.
The second sign is still in Korean, but they just made it look like Hindi
I am an Indian who knows Hangul too. You are right. The sign is in korean but looks like Devanagari script (Multiple languages like Marathi, Hindi and Nepali use this script). I must say that the way this has been done is brilliant! I was fooled too. (cuz I thought the script might be in other Indian language scripts like Bengali or Gujarati which look similar to Devanagari, until I noticed it was really in Hangul after reading your comment). Brilliant imitation!
