hieu va » hieu qua
xuc van » luc van, xuc ban, thuc van
duc van » duc va, duc tan, duc manh
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
vi cua » vai cua, di cua
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: te sac ky nang x hoi. ((lieu va) or (hieu va)) cam ((xuc van) OR (duc van)) hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang x hoi. ((lieu va) OR (hieu va)) cam ((xuc van) OR (duc van)) hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang x hoi. ((lieu va) or (hieu va)) cam ((xuc van) OR (duc van)) hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang x hoi. ((lieu va) or (hieu va)) cam ((xuc van) OR (duc van)) hanh vi cua triet*.
