Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
lam xuc » lam duoc
su sach » so sach, vu sach
van hoe » van hoa, van hoc, van hieu
ky dang » ky danh
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 ((ky dang) OR (ky nang)) van hoe. hieu van ((lam xuc) or (cam xuc)) va hanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ky dang) OR (ky nang)) van hoe. hieu van ((lam xuc) OR (cam xuc)) va hanh di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ky dang) OR (ky nang)) van hoe. hieu van ((lam xuc) or (cam xuc)) va hanh di cua triet*".
