All say "spring rain your such as oil", but this year the rain came so frequently. After the Spring Festival for several field of rain, to wake the sleeping winter.Sky gradually dim down, the earth on a layer of gauze shade, a large black cumulus cloud cover in people's heads.Rain, drop, drop or two, three drops... "Elf" one by one down in succession, they landed on the roof, "PI PI" sound, like calling on "cumulonimbus big bus" sisters down to play a game? My sisters has been reluctant to come down, naughty "elves" played the "board" on the roof. They slip from a rooftop to the ground, "with a swish with a swish" voice, singing the first symphony of spring.
