Perhaps you should try some spelling variations:
nhan viec » nhan vien, nhan viet, nha viec
thu sac » thu sach, thu san, thu xac
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
suc va » tuc va, luc va, soc va
cua tu » cua tuc, cua su, cua cu

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang xa hoi. hieu ve cac ((suc va) OR (duc va)) nhan viec ((cua te) OR (cua tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang xa hoi. hieu ve cac ((suc va) OR (duc va)) nhan viec ((cua te) or (cua tu))~".
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang xa hoi. hieu ve cac ((suc va) OR (duc va)) nhan viec ((cua te) or (cua tu))*.
