Can someone who is good at animation tell me why I assign a value to a biped object but can't?

[2829024262]

I use this method "node->SetNodeTM(t, transform);" to assign a value to a biped object,where the rotation value is:"-1.15917 -135.255 -2.99543",It can normally give the rotation value on the "Clavicle" to the set value.But when I give it a value of "68.267 -150.951 -3.27875",The value displayed in the scene changes "7.066 -123.895 41.457",the angle that causes the bones to be displayed at the end is wrong.

Is there a master in animation who can tell me how to solve it?
