Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
xuc van » duc van, vuc van, xuc ban
nang xa » nang x, lang xa, nang ma
luc van » luoc van, luu van, duc van
vi cua » vai cua, di cua
anh vi » hanh vi, anh va, anh ve
tu can » tu ban, tu cac, thu canh
can ky » van ky, dan ky, ban ky
va cai » va cac, va bai, va dai
ve cac » va cac, vien cac

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: tu can ky nang xa hoi. hieu ((va cai) OR (ve cac)) ((xuc van) OR (luc van)) anh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky nang xa hoi. hieu ((va cai) or (ve cac)) ((xuc van) OR (luc van)) anh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu can ky nang xa hoi. hieu ((va cai) or (ve cac)) ((xuc van) OR (luc van)) anh vi cua triet*.
