Bluebird Blossom by C.K. Tang

This is a large painting by C.K. Tang (nearly sofa art size!). My father discovered it in an antique store and loved both the painting and the frame. He was a frugal man and thought long and hard before spending over $100.00 to purchase it, but in the end, he could not resist. We are having trouble discovering anything about the artist. Someone stated that he was a Korean artist early 1900's, but are not certain of this fact. Can anyone enlighten us? Thank you!
