Perhaps you should try some spelling variations:
te sach » toc sach
nang ma » tang ma, sang ma, nang cao
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
hanh di » hanh vi, hanh de, hang di
cua tre » cuu tre, cua triet, dua tren
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va
cua te » cua tu

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 x) or (nang ma)) hoi. hieu ve cam xuc va hanh di ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang x) OR (nang ma)) hoi. hieu ve cam xuc va hanh di ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang x) or (nang ma)) hoi. hieu ve cam xuc va hanh di ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang x) or (nang ma)) hoi. hieu ve cam xuc va hanh di ((cua tre) OR (cua te))*.
