Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
van nang » van quang, van ban, van dong
sach dao » lanh dao
hieu van » hieu va, thien van, lieu va
vai cua » dai cua, hai cua, lai cua
tuc tat » tuc tap, tuc hat, tuc tao
su sach » so sach, vu sach
lang ha » long ha
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
tuc ta » tuc tap, tuc tao, tuc xa

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: su sach dao ((nang xa) OR (lang ha)) hoi. hieu van nang ((tuc ta) OR (tuc tat)) thanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach dao ((nang xa) or (lang ha)) hoi. hieu van nang ((tuc ta) OR (tuc tat)) thanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: su sach dao ((nang xa) or (lang ha)) hoi. hieu van nang ((tuc ta) OR (tuc tat)) thanh vai cua tre*.
