Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cua cau » cua cac, cua chu, cua cay
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
luc va » duc va, tuc va
loc va » hoc va
cua cu » cua chu, cua su, cua co

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang xa hoi. hieu ve cac ((luc va) OR (loc va)) danh cho ((cua cu) or (cua cau))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ve cac ((luc va) OR (loc va)) danh cho ((cua cu) OR (cua cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ve cac ((luc va) OR (loc va)) danh cho ((cua cu) or (cua cau))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ve cac ((luc va) OR (loc va)) danh cho ((cua cu) or (cua cau))*.
