Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
thien van » thi van
dau truc » cau truc, dai truc, doan truc
va thanh » gia thanh, ban thanh, va tinh
truc va » thuc va, thuc vat, trung va
cua tre » cua te, cua triet, dua tren
sach ky » sac ky, sach ty, sach kem
van dau » van dao, phan dau
nang xa » nang x, lang xa, nang ma
cuu tre » cau tren, cau treo

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 ky) OR (sach y)) nang xa hoi. thien van dau truc va thanh vai ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sach y)) nang xa hoi. thien van dau truc va thanh vai ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sach y)) nang xa hoi. thien van dau truc va thanh vai ((cua tre) OR (cuu tre))*.
