Perhaps you should try some spelling variations:
te sach » toc sach
van hau » van ha, van hai, van dau
sach ty » sach y, sach tu, sach thu
cua tre » cua te, cuu tre, cua triet
van cac » van hac, van cau, van bac
nang co » nang cao, nang doc, nang noi
ty nang » ky nang, ty xang, ty hang
co hoi » co hoc, co loi
bo van » vo van, so van, ho van
do van » dao van, vo van, so van
vi cua » vai cua, di cua

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 co hoi. hieu ((van cac) or (van hau)) ((bo van) OR (do van)) hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang co hoi. hieu ((van cac) OR (van hau)) ((bo van) OR (do van)) hanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang co hoi. hieu ((van cac) or (van hau)) ((bo van) OR (do van)) hanh vi cua tre*".
