Perhaps you should try some spelling variations:
te sach » toc sach
hanh ve » hanh vi, hanh va, hanh kem
hanh de » hanh kem
luc van » luoc van, luu van, duc van
cau luc » cau truc, cau phuc
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
mai hoi » mai khoi, dai hoi, lai hoi
y nang » ky nang, ly nang, v nang
ma hoi » xa hoi, ma hoa, me hoi
ve cau » ke cau, va cau, ve cac

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 y nang ((ma hoi) or (mai hoi)). hieu ve cau luc van ((hanh de) OR (hanh ve)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ((ma hoi) OR (mai hoi)). hieu ve cau luc van ((hanh de) OR (hanh ve)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((ma hoi) or (mai hoi)). hieu ve cau luc van ((hanh de) OR (hanh ve)) cua tre*".
