Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
te sach » toc sach
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
vai cua » dai cua, hai cua, lai cua
y nang » ky nang, ly nang, v nang
cuu va » cuu van
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. hieu ve cham ((cuu va) OR (cuu ve)) hanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. hieu ve cham ((cuu va) OR (cuu ve)) hanh vai cua te*.
