汉字雨，为什么上面横下面点？

The top line of yu looks like the sky. 雨字上面一横，像天上的云。 The little dots below are falling drops. 下面四个小点，就是落下的雨滴。 Old drawings of rain looked like this. 古人画雨，就是这个样子。 A cloud line with drops below. 上面一条云，下面落雨点。 As writing changed, it became neat squares. 写字慢慢变整齐，就成了方方正正。 So yu shows rain falling from the sky. 所以雨字就是天上在下雨。
