Perhaps you should try some spelling variations:
sach thien » sach thieu, sach tien, cach thien
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
xuc van » duc van, luc van, xuc ban
hieu ve » hieu va, hieu van
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
cuu tre » cua tre, cau tren, cau treo
ve cam » ve cham, ve cac, va cam
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 thien ((nang xa) OR (nang ma)) hoi. hieu ve cam xuc van hanh vi ((cua te) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thien ((nang xa) OR (nang ma)) hoi. hieu ve cam xuc van hanh vi ((cua te) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thien ((nang xa) OR (nang ma)) hoi. hieu ve cam xuc van hanh vi ((cua te) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: te sach thien ((nang xa) OR (nang ma)) hoi. hieu ve cam xuc van hanh vi ((cua te) or (cuu tre))*.
