Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van chat » cao chat
van hanh » van thanh, ban hanh, van anh
sach van » sach han, sach va, bach van
hanh di » hanh vi, hanh de, hang di
xuc van » duc van, luc van, vuc van
su sach » so sach, vu sach
van cau » van dau, van hau, toan cau
nang xa » lang xa, nang ma, mang xa
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: su sach van ((nang xa) or (nang x)) hoi. thien ((van cau) OR (van chat)) xuc van hanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach van ((nang xa) OR (nang x)) hoi. thien ((van cau) OR (van chat)) xuc van hanh di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach van ((nang xa) or (nang x)) hoi. thien ((van cau) OR (van chat)) xuc van hanh di cua triet*".
