cau luc » cau truc, cau phuc
cua tre » cua te, cuu tre, dua tren
hanh ca » hanh cac, hanh cat, hanh cua
cam luc » cam xuc
va hanh » van hanh, va thanh, va danh
tu bat » tu ban, tu dat
bat ky » ban ky, bac ky
nang o » nang co, nang ho, nang ro
o hoi » co hoi, o hoc, o hai

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu bat ky nang o hoi. lieu va ((cam luc) OR (cau luc)) va hanh ca ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu bat ky nang o hoi. lieu va ((cam luc) OR (cau luc)) va hanh ca ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu bat ky nang o hoi. lieu va ((cam luc) OR (cau luc)) va hanh ca ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: tu bat ky nang o hoi. lieu va ((cam luc) OR (cau luc)) va hanh ca ((cua tre) or (cua triet))*.
