The creation of facial expression:
- ended up using the good old way of creating facial expressions that i have learned in 2000 (that's when the maya version was 2.0 or 3.0)
- duplicate the face/head --> slice the duplicated face/head into lf_eye, rt_eye, lf_mth, rt_mth, lf_headbk, rt_headbk --> Create different blendshapes as expressions --> Create the blendshape relationships --> Wrap the sliced head with the original head
- reason is I could not figure out a better way of creating blend shapes that the left and right sides are perfect symmetry.
- the shapes of the left and right blendshapes should be symmetrical, yet the construction of facial expressions should allow the flexibility of having asymmetrical facial expressions, eg

- a possible solution should be using the transfer attribute command, but i could not figure out how it can be used.
