In autumn, I went to Zhongshan Park to see ginkgo. I came out from the east gate and didn't enter the Forbidden City. I just went east along the moat. I passed the corner building in the southeast corner of the Forbidden City and went north along the city wall to the Donghua Gate of the Forbidden City. Donghuamen flat rectangle, red city platform, white jade sumizu, 3 coupon doors, coupon caves outside the inner circle. There are city buildings on the city platform, yellow glazed tiles are heavy hall roof, and the base is surrounded by Han white jade railings. The city floor is 5 wide, surrounded by corridors, and Liang Yu has painted ink line gold spindle color paintings. A bridge in front of Donghua Gate crosses the moat and connects Donghuamen Street.
