Question

2. *Chuseok* is a big holiday of Korea.
----------------------------------------
Can we use both sentences? What is the difference between 'in Korea' and 'of Korea'? Does 'in Korea' modify 'a big holiday'? Does 'of Korea' modify 'a big holiday'?

Answer 1

I think it would be in Korea, simply because it's more proper.
