My Life Beautiful Night (Original)

Last night a strong wind, the temperature suddenly cold, the wind com, the fog go , fine weather, put on a down jacket, yesterday Lushan have the snow, if the big snow, I will take you to see, This is the evening shot in the lake a few landscape, although this tower is pirated buildings, night view is still very beautiful, the winter night is always too early, less than 6 pm, the day was dark.
Why the winter will be cold, summer will be hot, dark winter to early, dark in the summer to be late. This problem many people may not have studied, I really understand the problem is that many years ago I made a software, the world clock
Because the sun in the summer, very close to the distance from the Earth, the Mid-Autumn Festival, which is China's Lunar August 15 each year, the sun away from the Earth far from the Mid-Autumn Day means (day and night) time is equal

昨晚一场大风，气温骤降，风来雾走，天气晴好，穿上了羽绒服，庐山昨天下起了小雪，以后下大雪时，再带你们上去看一看，
这是刚刚傍晚在湖边拍摄的几张风景照，虽说这个塔是盗版建筑，夜景还是很漂亮，冬天的夜晚总是来得很早，不到下午6点，天就黑了.
为什么冬天会冷，夏天会热，冬天天黑的要早，夏天天黑的要晚. 这个问题许多人可能没有去研究过, 我真正理解这个问题是在许多年前我做一个三维地图世界时钟软件, 要去了解世界各个国家的时间和时差，并显示在一个圆形的三维地球上， 那个时候Google的Earth 还没有开发出来，我购买了一个地球插件调用美国宇航局(nasa)的地图时，才知道答案
因为太阳在夏季，太阳离地球的距离很近，中秋节，也就是中国每年农历8月15，太阳离地球距离远来远　中秋的意思是（白天和黑夜）时间正好相等， 农历8月15之后，太阳距离地球会越来越远，冬天也就快来了！
