Perhaps you should try some spelling variations:
thanh van » thanh san, thanh toan, thanh phan
thanh ve » hanh ve, thanh va, thanh vien
te sach » toc sach
xuc van » duc van, luc van, vuc van
cao xuc » cam xuc, cao duc, cao suc
su hien » su kien, su tien, thu hien
hieu va » lieu va, hieu qua
vu dang » su dang, vu quang, cua dang
vu nang » vuc nang, va nang, v nang
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: te sach ((vu nang) OR (vu dang)) x ho. hieu va cao xuc van ((thanh ve) or (thanh van)) su hien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((vu nang) OR (vu dang)) x ho. hieu va cao xuc van ((thanh ve) OR (thanh van)) su hien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((vu nang) OR (vu dang)) x ho. hieu va cao xuc van ((thanh ve) or (thanh van)) su hien".
• Adding a wildcard symbol may retrieve word variants: te sach ((vu nang) OR (vu dang)) x ho. hieu va cao xuc van ((thanh ve) or (thanh van)) su hien*.
