Perhaps you should try some spelling variations:
nhan dien » nhan vien, nhan dan, toan dien
nhan dieu » nhung dieu, nhan vien
thu sac » thu sach, thu san, thu xac
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cua te » cua tu
luc va » tuc va, loc va
sac ky » cac ky, sai ky
va cao » va cac, va co, va dao

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang xa hoi. hieu va cao ((duc va) or (luc va)) ((nhan dien) OR (nhan dieu)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang xa hoi. hieu va cao ((duc va) OR (luc va)) ((nhan dien) OR (nhan dieu)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang xa hoi. hieu va cao ((duc va) or (luc va)) ((nhan dien) OR (nhan dieu)) cua te*".
