Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
te sach » toc sach
sach ty » sach y, sach tu, sach thu
tai cua » thai cua, tai cuc, tri cua
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
luc va » duc va
loc va » hoc va
tuc va » thuc va, truc va, tuc xa
va cam » va cham, va cac, va cao

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 xa hoi. lieu va cam ((((luc va) OR (loc va))) or (tuc va)) hanh tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. lieu va cam ((((luc va) OR (loc va))) OR (tuc va)) hanh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. lieu va cam ((((luc va) OR (loc va))) or (tuc va)) hanh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. lieu va cam ((((luc va) OR (loc va))) or (tuc va)) hanh tai cua tre*.
