Perhaps you should try some spelling variations:
su triet » su tien, ve triet
hanh doi » thanh doi, hanh noi, hang doi
van hanh » van thanh, ban hanh, van anh
dang van » hoang van, hang va
cao xuc » cam xuc, cao duc, cao suc
xuc van » duc van, luc van, vuc van
su viet » so viet
sang ky » sang kyo, dang ky, tang ky
hieu va » lieu va, hieu qua
van hoi » van hoa, van hoc, van hoe
dan ky » van ky
va cao » va cac, va co, va dao

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sang ky) or (dan ky)) dang van hoi. hieu va cao xuc van hanh doi ((su triet) OR (su viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sang ky) OR (dan ky)) dang van hoi. hieu va cao xuc van hanh doi ((su triet) OR (su viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sang ky) or (dan ky)) dang van hoi. hieu va cao xuc van hanh doi ((su triet) OR (su viet))*".
