Heavy Rain  Capitalize your words in a title.

It's lucky。 I was lucky.  The heavy rains came just when I reached home. When I got back home，it began a heavy rain。 Today is one of those solar terms the Chinese had defined for the year - "the rains of the grains" (穀雨). 1  today is “谷雨” ，the Lunar Solar Terms。Spring rain is good to for farming.   in spring。
Tomorrow,  I’m going to have a two-days vacation trip.  I hope it will the weather will be a good weather。

1.  Another reason I hated such drastic simplification - using the sound instead.  Creates chaos by the "one-to-many correspondence".  I bet you understand it as the "Rain of the Valley"!  Another pet peeve - making 鬆 and 松 equivalent.
