Who can explain the phenomenon of the corner tower of the Forbidden City in Beijing

The Forbidden City, the corner tower, the river, the wild geese, Beijing here is simply the earthly beauty of the blue sky and yellow leaves 😝 The beauty of the combination of rigidity and softness in Eastern ancient architecture is even more prominent under the blue sky and white clouds ☁️, showing the ancient majesty. The classic photo 📷 spot is at the northwest corner outside the Forbidden City, no need to go into the Forbidden City Museum 😯 Just outside the moat of the Forbidden City, you can directly locate 📍 to the Shenwu Gate of the Forbidden City, which is the north gate of the Forbidden City, turn right ➡️ about 100 meters, when you get there you actually don't need to look for it, the place where the cameras 📹 are piled up is right 🤪
