Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec cac » vien cac, viec cua, viec lam
nang xa » nang x, lang xa, nang ma
vi cua » vai cua, di cua
luc va » duc va, tuc va, loc va
xuc va » duc va, tuc va, xac va
sac ky » cac ky
cua te » cua tu

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