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