What is the gift tax in Korea?

Could you kindly enlighten me about the gift tax regulations in Korea? I'm curious to know if there's a specific limit on the value of gifts that are subject to taxation, and what the tax rates are. Additionally, I'm interested in knowing if there are any exceptions or exemptions available for certain types of gifts. Would it be possible to provide an example of how the gift tax is calculated in a real-world scenario? Thank you for your time and assistance.
