Today someone asked in my QQ group how to make the curved lines in the picture above. I simply made it for your reference.
First use the Photoshop pen tool to outline the path.
Then convert the path into a selection.
First create a new layer, and then fill it with the gradient. You can first choose a pink for the foreground color, white for the background color, and then use a gradient from the foreground color to the background color.
When filling the selection, from top to bottom (reverse the operation when the direction option is selected), you can hold down the Shift key.
Execute the "Filter>Blur>Motion Blur" command and set it as shown in the figure.
Click the "OK" button and get the result as shown below.
Then re-call the originally created path in the Path palette.
Use the Direct Selection tool to change the shape of the path.
Create a selection based on a path.
Create a new layer, execute the "Edit > Stroke" command, set the stroke to 1 pixel, and deselect (Ctrl+D).
Use an eraser to erase unnecessary parts.
