I just finished The Longest Day in Chang'an (2019) and really enjoyed it. I found that the novel this drama is based on is written by Ma Bo Yong. Do you know any other drama that's adapted from his novels?

Thank you for the link, but this list is for the dramas where he's the screenwriter, not the author of the novel, although I see there are overlaps between these two roles.

Anyway, I'm asking here, in case there are dramas where he's the author but not the screenwriter, so that it's not listed in the link you provided above. I found a list of his novel in Wikipedia and I see some of his novels that have been adapted are The Secret of Three Kingdoms, the three Antique dramas, and Feng Qi Long Xi. But I just want to make sure in case there are others that I missed.
