van nang » van quang, van ban, van dong
thuc va » thuc vat, thuc dan, thuc day
su sach » so sach, vu sach
hieu va » lieu va, hieu qua
v nang » va nang, vu nang, voi nang
vi cua » vai cua, di cua
va cam » va cham, va cac, va cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((v nang) OR (van nang)) xa hoi. hieu va cam ((thuc va) or (truong va)) hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((v nang) OR (van nang)) xa hoi. hieu va cam ((thuc va) OR (truong va)) hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((v nang) OR (van nang)) xa hoi. hieu va cam ((thuc va) or (truong va)) hanh vi cua triet*".
