Perhaps you should try some spelling variations:
thanh dat » thanh san, thanh hai, thanh van
toc sach » hoc sach, doc sach, thuoc sach
hanh tai » thanh tai, hang tai, han tai
hanh dai » hanh dao, vanh dai, thanh dam
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
sach ty » sach y, sach tu, sach thu
cuu tre » cua tre, cau tren, cau treo
xuc va » duc va, tuc va, luc va
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: toc sach ty xang x hoi. hieu va cac xuc va ((((hanh dai) OR (thanh dat))) or (hanh tai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ty xang x hoi. hieu va cac xuc va ((((hanh dai) OR (thanh dat))) OR (hanh tai)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ty xang x hoi. hieu va cac xuc va ((((hanh dai) OR (thanh dat))) or (hanh tai)) cuu tre*".
