te sach » toc sach
hieu ve » hieu va, hieu van
lam cua » nam cua, lam chat
cua tre » cua te, cuu tre, cua triet
y sang » duy sang
_ sang » _ san
ma hoi » mai hoi, xa hoi, ma hoa

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y sang) OR (_ sang)) ma hoi. hieu ve ((pham duy) or (pham duc)) gia thanh lam cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y sang) OR (_ sang)) ma hoi. hieu ve ((pham duy) OR (pham duc)) gia thanh lam cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y sang) OR (_ sang)) ma hoi. hieu ve ((pham duy) or (pham duc)) gia thanh lam cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((y sang) OR (_ sang)) ma hoi. hieu ve ((pham duy) or (pham duc)) gia thanh lam cua tre*.
