The Chinese embassy in Seoul is closed on holidays, is that Korean or Chinese holidays?

Hi,
I am looking into traveling this summer and I will need to apply for a visa, but I work during the week. I read that the embassy in Seoul is closed on holidays, but I was wondering if that is Korean or? Also, if it is closed on Korean holidays, is there another way to apply for it, because I will not be able to go during its' hours of operation.
Thank you,
Trina
