cau luc » cau truc, cau phuc
cuu tre » cua tre, cau tren, cau treo
cam luc » cam xuc
hieu va » lieu va, hieu qua

y lang » o lang, _ lang, tay lang

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 y lang xa hoi. hieu va ((cam luc) OR (cau luc)) gia ((hanh vi) or (thanh va)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y lang xa hoi. hieu va ((cam luc) OR (cau luc)) gia ((hanh vi) OR (thanh va)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y lang xa hoi. hieu va ((cam luc) OR (cau luc)) gia ((hanh vi) or (thanh va)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach y lang xa hoi. hieu va ((cam luc) OR (cau luc)) gia ((hanh vi) or (thanh va)) cuu tre*.
