One of the techniques of learning how to root to the ground is to imagine yourself become a tree.  You can use this image while you are practicing the wuji method (in a standing posture just like the beginning of the LCUPCD method.) You can also use this image to adjust your posture while practicing the Three-Center Merged Standing method.

The following picture of a root-curved statue will give you an idea how you could imagine yourself become a tree.
