Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
te sach » toc sach
soc ban » coc ban, so ban, soc ba
vai cua » dai cua, hai cua, lai cua
hoc ban » hoc bang, hoc dan, hoc bai
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
ly nang » ly hang, ly vang, ly quang
cua te » cua tu
o hoi » co hoi, o hoc, o hai

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 ((ly nang) OR (ky nang)) o hoi. hieu ve cham ((soc ban) OR (hoc ban)) thanh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ly nang) or (ky nang)) o hoi. hieu ve cham ((soc ban) OR (hoc ban)) thanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach ((ly nang) or (ky nang)) o hoi. hieu ve cham ((soc ban) OR (hoc ban)) thanh vai cua te*.
