Perhaps you should try some spelling variations:
thanh van » thanh san, thanh toan, thanh phan
te sach » toc sach
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc va
xuc va » duc va, tuc va, xac va
ve cam » ve cham, ve cac, va cam

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