Is anyone here who have interest in "Haiku"....

The trick to haiku is: The haiku has to make sense as a 'sentence' as well as meeting the vowel-count requirement.

A traditional Japanese haiku goes:
Girls planting paddy [ie cơm, gạo fields]
Only their song
Free of mud.

As a sentence this reads "Girls planting paddy [have] only their song free of [the] mud [ie the mud of the cơm, gạo paddy]." Which makes sense in its own right - if bạn think it through.

I think the art form has to be considered as one would consider (say) a Japanese paper lantern hoặc paper screen. One can see what a hakiu is talking about - ie cơm, gạo paddy planting, tình yêu etc - but one sees it as though one were looking at the subject through a fine (rice) paper screen. It 'simplifies' the scene (how much can one see through rice/tissue paper?) but at the same time this 'simplification' gives one a new way of perceiving the subject.

So - "A lady/ And love/ Rainy" could be tinkered somewhat. It depends what bạn want to say. Is a lady in tình yêu like the rain hoặc a rainy day? Is tình yêu like rain? If so, how? That's what a haiku tries to capture/communicate. Perhaps:
Rain falls on
A lady; it
Is like love.

hoặc whatever it is bạn TRULY want to say.

i always thought that haiku had to have 5 letters in the 1st line, seven in the 2nd, and 5 again in the 3rd.....
then again, i've never studied it properly....

I like Haiku its preety nice!

I always thought that Haiku was like
1st line: 5 syllables
2nd line: 7
1st line: 5
like:

The hoa I pick
They dance with colors, like me
The màu sắc never fade

or

tình yêu is a Boulder
bạn can study it nicely
hoặc let the rock fall

i like the 2nd one

A haiku is a short,timed thi ca that expression throught a 5-7-5 syllabes.
bạn have to expell your image that is ephemer.Meaning it doesn't stay too long.

Nhật Bản origin, they have to compress their sensation,season into small line. The best option is figure of style,compar it to another object,material hoặc double sense.

Your's is dry,only 4 syllabes to each vers (Tetrasyllabe) and not so expressif.The text give bạn an illusion of being an haiku since the 2nd one is long to others snce bạn can do a 7 syllabes one.
But it doesn't mean that bạn have to stop, the road to a better haiku is long and expression and idea clasing will make bạn a better writter.
The road may be long but bạn can do it.
