Perhaps you should try some spelling variations:
va thanh » ban thanh, va tinh, le thanh
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
cua tre » cua te, cuu tre, cua triet
ve cac » va cac, vien cac
ve cua » le cua, de cua, te 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) OR (gia thanh)) ve 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) OR (gia thanh)) ve 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) OR (gia thanh)) ve cua tre*.
