I watched The Longest Day in Chang'an for Zhou Yi Wei after seeing The Rebel Princess, but I wound up really, really enjoying it. I would absolutely recommend it to someone. It's set up as a detective/investigation story, but the characters were the real draw. The story was really compelling and I thought that the relationship between Zhang Xiao Jing and Long Bo/Xiao Gui was so rich!

On top of that, the production design was absolutely amazing throughout. The costumes! The sets! The lantern tower! 10/10.
