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

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

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