vai cua » dai cua, hai cua, lai cua
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, cua triet
tu cong » thu cong, te cong, tai cong
tu nang » tru nang, tu nong, tu nano
co tuc » co thuc, co tu, do tuc
co toc » cao toc, co hoc, co doc

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((tu nang) or (tu cong)) xa hoi. hieu va ((co tuc) OR (co toc)) xa thanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tu nang) OR (tu cong)) xa hoi. hieu va ((co tuc) OR (co toc)) xa thanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tu nang) or (tu cong)) xa hoi. hieu va ((co tuc) OR (co toc)) xa thanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((tu nang) or (tu cong)) xa hoi. hieu va ((co tuc) OR (co toc)) xa thanh vai cua tre*.
