Perhaps you should try some spelling variations:
chat xuc » chat huu, cam xuc, chat cua
ban hanh » ban hang
va triet » va thiet, va trien, ve triet
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, me hoi
vi va » vi van, vai va, vu va

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: tu sach y nang ((ma hoi) OR (ma hoa)). hieu ve ((chat xuc) OR (chao xu)) ban hanh vi va triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang ((ma hoi) OR (ma hoa)). hieu ve ((chat xuc) or (chao xu)) ban hanh vi va triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang ((ma hoi) OR (ma hoa)). hieu ve ((chat xuc) or (chao xu)) ban hanh vi va triet*.
