The word "intrigue" used to mean that the building was exquisitely laid out, surrounded by a circle and staggered cornices, but now it means that each uses his own brains to compete in the dark.
This word comes from Du Mu's masterpiece Epanggong Fu in Tang Dynasty:
"Five steps on the first floor, ten steps and one pavilion, the back of the corridor, the high teeth, each holding the terrain, intrigue."
I hope I can solve your doubts. Welcome to communicate!
