Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cac tuc » cac toc, cac tu, cac tac
ve cac » va cac, vien cac
tuc va » thuc va, truc va, tuc xa
ve cua » de cua, te cua, ve cum
le cua » ly cua

You may be able to get more results by adjusting your search query.

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