comment How to Simplify equations over a Ring with Mathematica?
Nice. But it seems that the option Modulus is not capable to use with Simplify or FullSimplify. I don't want to solve the equations, but just want to simplify the relations of equations. Any idea?

comment How to do substitution of variable with power in Mathematica?
cool. I just edited my original post with more details. It seems when I use ToExpression["la_1la_2"], MMa will treat l and a_i as separate variables, but I want to treat la as one variable. Any idea?

comment Any efficient way to make complete homogeneous symmetric functions in Mathematica?
The only little issue is 0-th order is not well defined, i.e. completeSymmetricPolynomial[0, {a, b, c, d}]
