Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
ban hang » ngan hang
te sach » toc sach
ky lang » ky nang, ky tang, tay lang
ky dang » ky nang, ky danh
nam xuc » cam xuc, nam xua, nam thuc
vi cua » vai cua, di 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 ((ky lang) OR (ky dang)) xa hoi. hieu van nam xuc ((ban hanh) or (ban hang)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky lang) OR (ky dang)) xa hoi. hieu van nam xuc ((ban hanh) OR (ban hang)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky lang) OR (ky dang)) xa hoi. hieu van nam xuc ((ban hanh) or (ban hang)) vi cua triet*".
