Perhaps you should try some spelling variations:
manh dai » manh hai, vanh dai, manh khai
nang xa » nang x, lang xa, nang ma
hieu ve » hieu van
hieu va » lieu va, hieu qua
xuc ban » cuc ban, quoc ban, xuat ban
duc ban » duc tan, duc van, dua ban
cua tre » cua te, cuu tre, cua triet
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky

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 va)) cam ((xuc ban) OR (duc ban)) manh dai 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 va)) cam ((xuc ban) OR (duc ban)) manh dai 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 va)) cam ((xuc ban) OR (duc ban)) manh dai cua tre*".
