There is an exhibition about Jijang Bodhisattva at the Buddhist Museum at Jogye Temple through January 16. (The museum is beneath the new building in the temple complex, and is closed Mondays.)
I don’t actually know anything about this exhibition! Its title is: “Leading beings from the hell realms to enlightenment“. It could be quite interesting, depending upon how they’ve used the older paintings and statues to illustrate how Jijang responds, even in the depths of hell, to those who are suffering.
