Perhaps you should try some spelling variations:
thien van » thi van
van thanh » ban thanh, van tuan
tru nang » tra nang, tri nang, truc nano
xuc van » duc van, luc van, vuc van
cau xuc » cam xuc, cau luc, cau truc
su sach » so sach, vu sach
tu lang » cu lang, tu lanh, xu lang
van cau » van dau, van hau, van chat
vi cau » va cau, di cau, viet cau
ve cau » ke cau, va cau, ve cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((tu lang) or (tru nang)) xa hoi. thien van cau xuc van thanh ((vi cau) OR (ve cau)) tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((tu lang) OR (tru nang)) xa hoi. thien van cau xuc van thanh ((vi cau) OR (ve cau)) tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((tu lang) or (tru nang)) xa hoi. thien van cau xuc van thanh ((vi cau) OR (ve cau)) tren".
• Adding a wildcard symbol may retrieve word variants: su sach ((tu lang) or (tru nang)) xa hoi. thien van cau xuc van thanh ((vi cau) OR (ve cau)) tren*.
