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
su sach » so sach, vu sach
xuc van » duc van, luc van, vuc van
cau xuc » cam xuc, cau luc, cau truc
van cau » van dau, van hau, van chat
tu nang » tu nong, tu nano, tu lang
va cuu » va cau, va huu
va chu » va che, va cau, va chi

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