Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va hanh » van hanh, va thanh, va danh
truc va » thuc va, thuc vat, trung va
va cham » va chat, va tham
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
vu sach » vu bach, su sach, vu khach
y nang » ky nang, ly nang, v nang
vi cua » vai cua, di cua
va cam » va cac, va cao, va cai

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: ((so sach) OR (vu sach)) y nang xa hoi. hieu ((va cam) OR (va cham)) truc va hanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (vu sach)) y nang xa hoi. hieu ((va cam) OR (va cham)) truc va hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (vu sach)) y nang xa hoi. hieu ((va cam) OR (va cham)) truc va hanh vi cua triet*.
