看一下这张图片，这就是中国东北的冬天，白雪皑皑，天气非常寒冷。我们在看一下这张图片，这是肇庆七星岩的冬天，到处都是一片绿色。肇庆冬天的时候你是否感到非常寒冷？再看一下这张图片，北方装暖气是很普遍的现象，但为什么我们南方不装暖气呢？
所以我们可以得出结论，空调或其他取暖方式比暖气更适合也更划算。
Look at this picture, which is in northeast China's winter, snow, the weather is very cold. We look at this picture, it is winter in Zhaoqing Seven Star Crags, a green everywhere. Zhaoqing winter, when you feel very cold? Look at this picture, Northern Heating equipment is a very common phenomenon, but why we do not install heating it south?
So we can conclude that the air conditioning or other heating method is more suitable and more cost-effective than heating.
