Perhaps you should try some spelling variations:
danh vai » danh sai, danh va, doanh van
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
ve cac » vien cac
toc xa » toc ta, hoc xa, tac xa

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 ky nang xa hoi. hieu ((ve cac) or (va cac)) ((toc xa) OR (tuc xa)) danh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ((ve cac) OR (va cac)) ((toc xa) OR (tuc xa)) danh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ((ve cac) or (va cac)) ((toc xa) OR (tuc xa)) danh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. hieu ((ve cac) or (va cac)) ((toc xa) OR (tuc xa)) danh vai cua tre*.
