sach ty » sach y, sach tu, sach thu
vai cua » dai cua, hai cua, lai cua
va danh » va dinh, va dan, dia danh
va hanh » van hanh, va thanh, ban hanh
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ty nang » ky nang, ty xang, ty hang

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

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