Perhaps you should try some spelling variations:
su triet » su viet, su tien
ve triet » va trien
nang xa » nang x, lang xa, nang ma
ve chat » va chat, van chat
va hanh » van hanh, va thanh, va danh
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky
ve cam » ve cham, ve cac, va cam

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 san ky nang xa hoi. hieu ((ve cam) OR (ve chat)) tu va hanh vi ((su triet) OR (ve triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang xa hoi. hieu ((ve cam) or (ve chat)) tu va hanh vi ((su triet) OR (ve triet))~".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang xa hoi. hieu ((ve cam) or (ve chat)) tu va hanh vi ((su triet) OR (ve triet))*.
