thai cua » than cua, tai cuc, tri cua
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) OR (su cac)) ky nang xa hoi. thien van cam xuc ((va hanh) or (va danh)) thai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cac)) ky nang xa hoi. thien van cam xuc ((va hanh) OR (va danh)) thai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su cac)) ky nang xa hoi. thien van cam xuc ((va hanh) or (va danh)) thai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su cac)) ky nang xa hoi. thien van cam xuc ((va hanh) or (va danh)) thai cua triet*.
