Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
chat xuc » chat huu, cam xuc, chao xu
ban hanh » ban hang
tu sach » thu sach, su sach, te sach
lai cua » dai cua, hai cua, lai chau
ve chat » va chat, van chat
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, ma hoa, me hoi
cua tu » cua tuc, cua su, cua cu

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 (xa hoi)). hieu ve chat xuc ((van thanh) OR (ban hanh)) lai cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang ((ma hoi) OR (xa hoi)). hieu ve chat xuc ((van thanh) or (ban hanh)) lai cua tu~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang ((ma hoi) OR (xa hoi)). hieu ve chat xuc ((van thanh) or (ban hanh)) lai cua tu*.
