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
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien 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 xa hoi. hieu ((ve cam) or (ve cac)) 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 nang xa hoi. hieu ((ve cam) OR (ve cac)) 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 nang xa hoi. hieu ((ve cam) or (ve cac)) duc ((tan hanh) OR (tan thanh)) vi van trieu".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu ((ve cam) or (ve cac)) duc ((tan hanh) OR (tan thanh)) vi van trieu*.
