nang xa » nang x, lang xa, nang ma
hieu ve » hieu va
tu viet » te viet, nu viet, vu viet
su viet » so viet
cua tre » cua te, cuu tre, cua triet
so sac » so sach, so dac
sac ky » cac ky, sai ky
co cua » con cua, ca cua, cong cua

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

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