Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
va thanh » gia thanh, va tinh, le thanh
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cac » vien cac
vi cua » vai cua, di cua

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

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