Perhaps you should try some spelling variations:
tan thanh » tran thanh, tang thanh, toan thanh
van trieu » tan trieu, van tieu, van hieu
tan hanh » tang hanh, toan hanh, tran hanh
te sach » toc sach
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
cam duc » cam xuc, cao duc, pham duc
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 y ((lang xa) or (nang x)) hoi. hieu va cam duc ((tan hanh) OR (tan thanh)) vi van trieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((lang xa) OR (nang x)) hoi. hieu va cam duc ((tan hanh) OR (tan thanh)) vi van trieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang xa) or (nang x)) hoi. hieu va cam duc ((tan hanh) OR (tan thanh)) vi van trieu".
• Adding a wildcard symbol may retrieve word variants: te sach y ((lang xa) or (nang x)) hoi. hieu va cam duc ((tan hanh) OR (tan thanh)) vi van trieu*.
