thuc va » thuc vat, thuc dan, thuc day
va hanh » van hanh, va thanh, va danh
sach v » sach va, sach 2, sach vay
ve nam » he nam, le nam, te nam
va nam » van nam, ha nam, va nay
vi cua » vai cua, di cua

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) or (sach y)) nang xa hoi. hieu ((ve nam) OR (va nam)) thuc va hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach v) OR (sach y)) nang xa hoi. hieu ((ve nam) OR (va nam)) thuc va hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach v) or (sach y)) nang xa hoi. hieu ((ve nam) OR (va nam)) thuc va hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: su ((sach v) or (sach y)) nang xa hoi. hieu ((ve nam) OR (va nam)) thuc va hanh vi cua triet*.
