Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
qua phat » qua nhat, qua phan, que phat
te sach » toc sach
luc van » luoc van, luu van, duc van
dai cuu » dai cua, dai huu
cuu tre » cua tre, cau tren, cau treo
xuc ban » duc ban, cuc ban, quoc ban
sach ty » sach y, sach tu, sach thu
xuc van » duc van, vuc van, thuc van
ty nang » ky nang, ty xang, ty hang
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 nang x hoi. hieu qua phat ((((xuc van) OR (xuc ban))) or (luc van)) hanh dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang x hoi. hieu qua phat ((((xuc van) OR (xuc ban))) OR (luc van)) hanh dai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang x hoi. hieu qua phat ((((xuc van) OR (xuc ban))) or (luc van)) hanh dai cuu tre*".
