trung va » truong va, trang va, trung ha
vu sach » vu bach, su sach, vu khach
truc va » thuc va, thuc vat
hanh ca » hanh cac, hanh cat, hanh cua
y nang » ky nang, ly nang, v nang
ca cua » co cua
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sach y nang x hoi. lieu va cac ((duc va) or (((truc va) OR (trung va)))) hanh ca cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y nang x hoi. lieu va cac ((duc va) OR (((truc va) OR (trung va)))) hanh ca cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y nang x hoi. lieu va cac ((duc va) or (((truc va) OR (trung va)))) hanh ca cua triet".
• Adding a wildcard symbol may retrieve word variants: vu sach y nang x hoi. lieu va cac ((duc va) or (((truc va) OR (trung va)))) hanh ca cua triet*.
