dong cong » dung cong, dang cong, cong cong
cua triet » cua viet, su triet, va triet
vu sach » vu bach, su sach, vu khach
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
xuc xa » tuc xa, buc xa
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. ((hieu ve) or (lieu va)) cam xuc xa ((dong cong) OR (duong cong)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y nang x hoi. ((hieu ve) OR (lieu va)) cam xuc xa ((dong cong) OR (duong cong)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y nang x hoi. ((hieu ve) or (lieu va)) cam xuc xa ((dong cong) OR (duong cong)) cua triet".
• Adding a wildcard symbol may retrieve word variants: vu sach y nang x hoi. ((hieu ve) or (lieu va)) cam xuc xa ((dong cong) OR (duong cong)) cua triet*.
