va thanh » gia thanh, ban thanh, va tinh
hieu van » hieu va, thien van, lieu va
vu sach » vu bach, su sach, vu khach
cam luc » cam xuc
nang xa » nang x, lang xa, nang ma
cau luc » cau truc, cau phuc
y nang » ky nang, ly nang, v nang

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