Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van thanh » ban thanh, van tuan
hieu van » hieu va, thien van, lieu va
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa
soc van » hoc van, sac van, soc dan
hanh di » hanh vi, hanh de, hang di
te sach » toc sach
oc van » hoc van, luoc van, quoc van
di cua » dai cua, doi cua, de cua

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 ((nang xa) or (lang xa)) hoi. hieu van thanh ((soc van) OR (oc van)) hanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang xa) OR (lang xa)) hoi. hieu van thanh ((soc van) OR (oc van)) hanh di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) or (lang xa)) hoi. hieu van thanh ((soc van) OR (oc van)) hanh di cua triet*".
