Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va
cho cua » co cua, chi cua, cho ca
cua tre » cua te, cuu tre, cua triet
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
xuc va » tuc va, luc va, xac va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang xa hoi. ((hieu ve) OR (hieu van)) cac ((xuc va) or (duc va)) danh cho cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. ((hieu ve) OR (hieu van)) cac ((xuc va) OR (duc va)) danh cho cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. ((hieu ve) OR (hieu van)) cac ((xuc va) or (duc va)) danh cho cua tre*".
