Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van thanh » ban thanh
van tuan » van quan, van ban, anh tuan
van hanh » ban hanh, van anh, van ban
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
soc van » hoc van, oc van, sac van
hanh di » hanh vi, hanh de, hang di
te sach » toc sach
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) OR (van tuan)) soc 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) OR (van tuan)) soc 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) OR (van tuan)) soc van hanh di cua triet*".
