Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vai » thanh hai, thanh van, thanh tai
va thanh » gia thanh, ban thanh, va tinh
hieu van » hieu va, thien van, lieu va
nang van » dang van, tang van, lang van
van hoe » van hoa, van hoc, van hieu
nam xuc » nam xua, nam thuc, nam duoc
vu sach » vu bach, vu khach
vai cua » dai cua, hai cua, lai cua
su sach » so sach
y nang » ky nang, ly nang, v nang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) y nang van hoe. hieu van ((nam xuc) OR (cam xuc)) va thanh vai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) y nang van hoe. hieu van ((nam xuc) or (cam xuc)) va thanh vai cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) y nang van hoe. hieu van ((nam xuc) or (cam xuc)) va thanh vai cua triet*.
