Perhaps you should try some spelling variations:
thien van » thi van
thanh ve » hanh ve, thanh va, thanh vien
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
van cau » van dau, van hau, van chat
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
xuc va » tuc va, luc va, xac va

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 ty nang xa hoi. thien van cau ((xuc va) or (duc va)) thanh ve ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang xa hoi. thien van cau ((xuc va) OR (duc va)) thanh ve ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang xa hoi. thien van cau ((xuc va) or (duc va)) thanh ve ((cua tre) OR (cuu tre))*".
