From the perspective of geomantic omen, the east is full of yang, which is the so-called purple gas coming from the east. Auspicious qi can enter from the east window, which makes the house shrouded in auspiciousness.
The east is where the sun rises, symbolizing a new beginning. If there is a window in the east of the house, good luck symbolizing growth, development and prosperity will flood into the house. When you get up every morning, if you see the sun rising, people will feel surrounded by a thriving and developed atmosphere, which subconsciously has an environmental effect on people's growth. Residential windows are located in the east and west directions, and the lighting and ventilation effects are similar, but the morning sun collected in the east is better than the sunset in the west, and the wind inhaled in the east in spring and summer is much better than the cold wind received in the west in autumn and winter.
