Perhaps you should try some spelling variations:
lanh hai » manh hai, thanh hai, lang chai
danh hai » dang hai, manh hai, danh hau
cam luc » cam xuc, cau luc
nang xa » nang x, lang xa, nang ma
hieu va » hieu qua
te sac » te sach, te cac, te san
luc va » duc va, tuc va, loc va
sac ky » cac ky, sai 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: te sac ky nang xa hoi. ((hieu va) or (lieu va)) cam luc va ((danh hai) OR (lanh hai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. ((hieu va) OR (lieu va)) cam luc va ((danh hai) OR (lanh hai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. ((hieu va) or (lieu va)) cam luc va ((danh hai) OR (lanh hai)) cua te".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. ((hieu va) or (lieu va)) cam luc va ((danh hai) OR (lanh hai)) cua te*.
