va triet » va thiet, va trien, ve triet
duc van » duc va, duc tan, duc manh
dinh cu » dinh cuu, dinh chuc, dinh chi
nang xa » nang x, lang xa, nang ma
ve cam » ve cham, ve cac, ve cai
y nang » ky nang, ly nang, v nang
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: thu sach y nang xa hoi. hieu ((ve cam) or (va cam)) duc van ((dinh cu) OR (dinh chau)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang xa hoi. hieu ((ve cam) OR (va cam)) duc van ((dinh cu) OR (dinh chau)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang xa hoi. hieu ((ve cam) or (va cam)) duc van ((dinh cu) OR (dinh chau)) va triet".
• Adding a wildcard symbol may retrieve word variants: thu sach y nang xa hoi. hieu ((ve cam) or (va cam)) duc van ((dinh cu) OR (dinh chau)) va triet*.
