Wu-Liu-Ding　algebras,　that　is　D(m,　d,　xi),　are　a　class　of　non-pointed　affine　prime　regular　Hopf　algebras　of　GK-dimension　one.　In　this　paper,　we　mainly　study　a　class　of　quotient　algebras　of　D(m,　d,　xi),　denoted　by　D＇(m,　d,　xi),　which　are　2m(2)d-dimensional　non-pointed　semisimple　Hopf　algebras.　For　a　better　understanding　of　the　structure　of　the　Hopf　algebra　D＇(m,　d,　xi),　we　have　considered　the　Grothendieck　rings　of　D＇(m,　d,　xi)　and　their　Casimir　numbers　when　d　is　odd　in　our　previous　paper.　In　this　paper　we　continue　dealing　with　the　more　complex　case　when　d　is　even.　It　turns　out　that　the　Grothendieck　rings　of　D＇(m,　d,　xi)　are　generated　by　four　elements　subject　to　some　relations.　Then　we　give　the　Casimir　numbers　of　the　Grothendieck　rings　of　D＇(1,　d,　xi)　and　D＇(2,　d,　xi).
