Perhaps you should try some spelling variations:
danh hai » dang hai, lanh hai, manh hai
nang xa » nang x, lang xa, nang ma
hieu va » hieu qua
cam luc » cam xuc, cau luc
va danh » va dinh, va dan, va hanh
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
luc va » duc va, tuc va, loc va
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: te sac ky nang xa hoi. ((hieu va) or (lieu va)) cam luc va danh hai ((cua te) OR (cua tu))~.
• 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 ((cua te) OR (cua tu)).
• 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 ((cua te) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. ((hieu va) or (lieu va)) cam luc va danh hai ((cua te) OR (cua tu))*.
