At 4.5 pm, what is the house with sunshine?

When the sun comes out at 4-5 pm, people usually turn their heads to the north. It takes a long time to get hot sun in summer and a short time to get cold sun in winter, which is why the room facing north feels cold in winter. The sun shines in the morning, generally facing south or north and south. The sun exposure time is short in summer and short in winter, commonly known as warm in winter and cool in summer.
