nang xa » lang xa, nang ma, ang xa
mang xa » lang xa, mang may, dang xay
xuc van » duc van, luc van, vuc van
cach tu » cach thuc
hieu ve » hieu va, hieu van
vi cua » vai cua, di cua
cua su » qua su
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: te cach tu ((((nang xa) OR (mang xa))) or (nang x)) hoi. hieu ve cac xuc van hanh vi cua su~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cach tu ((((nang xa) OR (mang xa))) OR (nang x)) hoi. hieu ve cac xuc van hanh vi cua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cach tu ((((nang xa) OR (mang xa))) or (nang x)) hoi. hieu ve cac xuc van hanh vi cua su".
• Adding a wildcard symbol may retrieve word variants: te cach tu ((((nang xa) OR (mang xa))) or (nang x)) hoi. hieu ve cac xuc van hanh vi cua su*.
