What direction does the palace gate face?

Since ancient times, palace doors have been open to the south. This is from the perspective of Feng Shui and is related to the movement of Qi. Traditional Chinese medicine says that the north corresponds to the kidneys, which governs collection, and the south corresponds to the heart, which governs distribution and divergence. . The ancients sat north and faced south, and the north door could not be opened because it was necessary to hide the qi, while the south door was to let the qi out for balance.
