Perhaps you should try some spelling variations:
tinh day » tinh da, tinh dau, tinh dak
te sach » toc sach
sang xa » lang xa, sang ma, mang xa
song xa » song cua
hieu ve » hieu va, hieu van
cac duc » cac du, cao duc, cac dac
va tinh » may tinh
day cua » dai cua
cua te » cua tu

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 y ((sang xa) OR (song xa)) hoi. hieu ve ((cac duc) OR (giao duc)) va tinh day cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((sang xa) OR (song xa)) hoi. hieu ve ((cac duc) or (giao duc)) va tinh day cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach y ((sang xa) OR (song xa)) hoi. hieu ve ((cac duc) or (giao duc)) va tinh day cua te*.
