Perhaps you should try some spelling variations:
cau treo » cau theo, cau tren, cau triet
thanh vi » hanh vi, thanh va, thanh ve
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
hieu ve » hieu va, hieu van
ve coc » ve cuoc, ve cac, ve co
tuc va » thuc va, truc va, tuc xa
vi cau » va cau, ve cau, di cau

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (nang ma)) hoi. hieu ve coc ((tuc va) OR (duc va)) thanh vi cau treo~.
• Adding a wildcard symbol may retrieve word variants: tu sach y ((nang xa) or (nang ma)) hoi. hieu ve coc ((tuc va) or (duc va)) thanh vi cau treo*.
