THANK YOU TO ALL FOR PARTICIPATING IN THE FUN QUIZ.
This is the answer to the quiz on the buddha in Dongwasha Temple in South Korea.
The red circle on the buddha is bee hive.
As told by our korean guide that he asked the monks in the temple regarding the red circle and was told it was bee hive and not bird nest. (It was a neat nest and not untidy so could not be bird nest.) Those who guess it was bird nest, you are very close to the answer, well done.
No one guess it correct.
I also thought it was some kind of CCTV.
