What is considered a millionaire in Korea?

Excuse me, I'm quite curious about the financial standards in Korea. Could you possibly enlighten me on what is considered a millionaire status in your country? I understand that the value of currency and cost of living can vary significantly from one place to another, so I'm hoping to get a more local perspective on this matter. I'm also interested in knowing if there are any specific thresholds or benchmarks that are widely recognized as indicating wealth or success in Korean society. Thank you for your time and assistance.
