No, they don’t have a flood story. They have a creation story. And the garden of Eden, fall, Tower of Babel and flood seem to be part of the Chinese alphabet at one time at least - and he seems to indicate some of them are current. Even if one of these characters holds up, that’s interesting. If they all do, that’s really impressive.
After I saw this video, I checked out to see whether this holds up. It seems the creation story does and the characters probably do, but the pastor in the video was part of a huge scandal and went to prison. So that’s obviously not great - yikes! But the presentation is still interesting - especially as he writes out the characters. Also it’s interesting to see what a megachurch in Asia is like…all the clapping is not my style…but oh well
