danh nam » dan nam, dinh nam, dang nam
sanh ty » sach ty, canh tay
hieu ve » hieu va, hieu van
so sanh » do sanh
nang xa » lang xa, nang ma, mang xa
ve chat » va chat, van chat
huu va » tuu va
cuu va » cuu van, cuu ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sanh ty ((nang xa) or (nang x)) hoi. hieu ve chat ((huu va) OR (cuu va)) danh nam cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ty ((nang xa) OR (nang x)) hoi. hieu ve chat ((huu va) OR (cuu va)) danh nam cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ty ((nang xa) or (nang x)) hoi. hieu ve chat ((huu va) OR (cuu va)) danh nam cua viet*".
