Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
xach tay » canh tay
nam thuc » nam thuoc, am thuc, nam thu
thuc gia » thuc giai, thue gia, thuc dia
sach ty » sach tu, sach thu, sach hay
hang xa » hoang xa, hang va, hang ca
hieu ve » hieu va, hieu van
ve nam » he nam, va nam, le nam
cua su » qua su

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: vu ((xach tay) OR (((sach ty) OR (sach y)))) hang xa hoi. hieu ve nam thuc gia thanh dai cua su~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((xach tay) or (((sach ty) OR (sach y)))) hang xa hoi. hieu ve nam thuc gia thanh dai cua su~".
• Adding a wildcard symbol may retrieve word variants: vu ((xach tay) or (((sach ty) OR (sach y)))) hang xa hoi. hieu ve nam thuc gia thanh dai cua su*.
