Who made the feng shui design of the Forbidden City?

A.D. 1267- 1283, which lasted 16 years, built the famous capital of the Yuan Dynasty in the history of China. The designers are the great hydraulic scientist Guo Shoujing and his teacher Liu. These two men are proficient in astronomy, geography, calendar, water conservancy, and more importantly, they are both proficient in easy learning. After Kublai Khan unified the whole country, he asked Liu where he could build his capital. Liu said that the capital of the Yuan Dynasty was short, while the capital of Yanjing was far away. Liu once suggested that Kublai Khan renamed Mongolia "Dayuan" in the Book of Changes, which was the origin of the Yuan Dynasty.

The Forbidden City in Beijing that we see now is the city of Beijing in the Ming Dynasty. On the basis of the Capital City of Yuan Dynasty, a series of large-scale renovations were carried out (as shown above), among which the most fundamental and key renovation was to retract the northern wall of Dadu City to the south in Wuhuali, and at the same time move the Imperial City of Da Nei (Forbidden City in Ming Dynasty) to the south accordingly. This change changed the geomantic omen of Beijing in Ming Dynasty compared with the metropolis in Yuan Dynasty, and changed the direct point of the city, that is, the center point.
