@slowwalker, We can get some meanings from Daewung-jeon Hall of Gaesim-sa Temple. I never seen or heard before beating the wood block. Yep it's small temple than previous. Seemed Gaesim-sa Temple tourist attractive location. Pagoda style same condition in Korea. Also window and roof patterns so impressive to me. Absolutely mind relaxation photo clicks you found in Gaesim-sa Temple. Thank you for explained.
