Perhaps you should try some spelling variations:
thanh lap » thanh san, phan lap, thanh hai
chau tre » chay tren, chau tho, cho tre
hanh lai » hanh lam, hanh tai, thanh loi
luc van » luoc van, luu van, duc van
te sach » toc sach
sach ky » sac ky, sach y, sach ty
xuc van » duc van, xuc ban, thuc van
hieu ve » hieu va, hieu van
ve cac » va cac, vien cac
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 ky nang x hoi. hieu ve cac ((xuc van) or (luc van)) ((hanh lai) OR (thanh lap)) chau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang x hoi. hieu ve cac ((xuc van) OR (luc van)) ((hanh lai) OR (thanh lap)) chau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang x hoi. hieu ve cac ((xuc van) or (luc van)) ((hanh lai) OR (thanh lap)) chau tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang x hoi. hieu ve cac ((xuc van) or (luc van)) ((hanh lai) OR (thanh lap)) chau tre*.
