Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
te sach » toc sach
sach ty » sach y, sach tu, sach thu
vai cua » dai cua, hai cua, lai cua
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
ty nang » ky nang, ty xang, ty hang
cuu va » cuu ve
cua te » cua tu
x hoi » o hoi, x ho, 5 hoi

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