Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
te sach » toc sach
sach ty » sach y, sach tu, sach thu
han tai » hang tai, nhan tai, van tai
cuu tre » cua tre, cau tren, cau treo
hieu va » lieu va, hieu qua
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
va cam » va cham, va cac, va cao
xang x » nang x
x hoi » xa hoi, o hoi, x ho

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 ty xang x hoi. hieu va cam ((xuc va) OR (tuc va)) ((hanh dai) or (han tai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty xang x hoi. hieu va cam ((xuc va) OR (tuc va)) ((hanh dai) OR (han tai)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty xang x hoi. hieu va cam ((xuc va) OR (tuc va)) ((hanh dai) or (han tai)) cuu tre*".
