thai cua » than cua, tai cuc, tri cua
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, cua triet
su xac » pu xac, su cac
xac ky » cac ky, sac ky, bac ky
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: su xac ky nang x hoi. ((hieu van) OR (lieu va)) chat xuc ((va hanh) or (va danh)) thai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky nang x hoi. ((hieu van) OR (lieu va)) chat xuc ((va hanh) OR (va danh)) thai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky nang x hoi. ((hieu van) OR (lieu va)) chat xuc ((va hanh) or (va danh)) thai cua tre*".
