Tang Mo's renovation of the Forbidden City was actually somewhat different from the real Forbidden City, as it made extensive use of glass, including floor-to-ceiling windows and other modern design elements in certain garden areas.
Anyway, Tang Mo had an abundance of glass at his disposal and could unabashedly install skylights overhead to enjoy the nighttime stars.
Although the overall red walls and green tiles of the Forbidden City still remained in Huaxia's style, its interior design leaned toward the modern.
After all, Tang Mo wasn't about to create headaches for himself by pursuing ultimate historical accuracy while ignoring the palace's practical functions.
I mean, could a palace fit for the future lack a parking lot and underground parking facility? Of course not; it had to have them, along with bomb shelters and helipads for helicopters.
