Perhaps you should try some spelling variations:
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
tu sac » tu sach, tu cac, tu san
tuc va » thuc va, truc va, tuc xa
xuc va » duc va, luc va, xac va
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
cua tu » cua tuc, cua su, cua cu

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