The museum amazing scientific "0.618" in the main building of the Forbidden City v are located in the North-South axis and the line on both sides. Ancient architect very particular about the three-dimensional distribution of science to various parts of the ratio between the best ratio. For example, when we step in the door one afternoon I stopped North door openings, there Wo-ping as around doors and Jau-Der on both sides of the door and door Fok, the best perspective. Why is this shown? There are two reasons: one, Tai Wo Gate Plaza things width 200 meters, 130 meters deep into the South and the North, 130:200 ratio of 0.65, is close to the ratio of 0.618, resulting in a spectacular wonderful perspective. Two, from mouth to the North Gate Gate Wo two things equal to the distance between, forming an angle of 60 degrees the equilateral triangle, and the best contrast ratio perspective. At the same time, when we entered the door canopies Wo Wo Dian stop and overlooks the square, a very spacious magnificent landscape has immediate. Why is there such a best visual? There are two reasons: one, Taihe Dian-high 35.03 meters (high-8.13 meters), body-yi and two House height of 23.78 meters, 200 square meters wide. East Court Square and width ratio of 11.89%. Dian Tai Kok than two meters high 11.25, a ratio of 0.678. With this rate of 0.618 ratio, the main object of Building and Plaza area ratio in the most ideal sense of perspective. 2, Wo door canopies and the Taihe Dian axis to the corner about two in 30,000 square meters of the square to form a 60-degree angle between the equilateral triangle, which is get the best angle reasons.
