Perhaps you should try some spelling variations:
changes made » changes a, changes due
yang chang » ying chang, huang chang, yang yang
chang you » change you, change your, thing you
tan yang » dan yang, tan ying, tan yong
you chen » you when, you chenli, you check
yang jie » yang jin, yang jui, yang xi
yang yi » yang xi, yang jui
