Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu quan » lieu quan, thien quan, lien quan
su cach » su sach, tu cach, su cac
cach tu » cach thuc
tu nang » tru nang, tu nong, tu nano
nang xa » nang x, lang xa, nang ma
xuc van » duc van, luc van, vuc van
van anh » van thanh, tuan anh, van minh
anh dai » vanh dai, anh bai, anh dat

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

• If you are trying to use Boolean operators, they must be ALL CAPS: su cach tu nang xa hoi. ((hieu qua) OR (hieu quan)) cam xuc van anh dai cua triet~.
• Adding a wildcard symbol may retrieve word variants: su cach tu nang xa hoi. ((hieu qua) or (hieu quan)) cam xuc van anh dai cua triet*.
