This five-character poem says: The south of the Yangtze River looks smoky under the infiltration of spring rain. There, I admire the blooming cherry blossoms and my heart is full of love. You can add two more sentences at the end to become a love poem:
The misty rain travels south of the Yangtze River,
The lingering love of cherry blossoms.
But please send the flowers and rain,
pass it to the beautiful lady.
It means that when visiting the spring scenery of Jiangnan, my heart is full of love, hoping that the petals of the cherry blossoms will fly to the beautiful woman and convey my love to her.
