Chinese brushwork, acrylic on canvas
The calligraphy style is cursive script. It has a soft background with falling green leaves. There should have been seven characters in the artwork; the sixth one (leaves) has been omitted and the artist drew falling leaves instead; a graphical ellipsis.
The meaning is "Do not listen to the rain in the forest." This is a verse from a Chinese poem. In other words, forget what people are doing in the storm, just enjoy your walk in the forest.
Give me a quote as you wish. I'll translate into Chinese.
