Perhaps you should try some spelling variations:
thanh dat » thanh san, thanh hai, thanh van
suu viet » su viet, sau viet, sieu viet
hanh dao » lanh dao, thanh dam, doanh dao
sach ky » sac ky, sach ty, sach kem
hieu va » lieu va, hieu qua
may hoi » may thoi, tay hoi, mai hoi
cao xuc » cam xuc, cao duc, cao suc
va cao » va cac, va co, va dao
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach y)) mang may hoi. hieu va cao xuc va ((hanh dao) or (thanh dat)) suu viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) mang may hoi. hieu va cao xuc va ((hanh dao) OR (thanh dat)) suu viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) mang may hoi. hieu va cao xuc va ((hanh dao) or (thanh dat)) suu viet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) mang may hoi. hieu va cao xuc va ((hanh dao) or (thanh dat)) suu viet*.
