1$\begingroup$ The image you are using to drive the displacement is a low quality one, most likely 8 bits per pixel. Not enough information to get a smooth transition from one height to the next. Read the links above. $\endgroup$– no-can-doCommented Jul 14, 2020 at 4:53

The problem has resolved. It is because of the texture image is 1k 8bit. So I used a 32bit 3K image to make the texture for rendering. During this problem, I also discovered Photoshop 3D filter makes pretty good bump and normal textures.
These two articles explained it very well.
How to get rid of the odd lines shown in the image?
Why does my displacement look jagged - Cycles?
Keep blending, be safe and peace.
