Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
xuc van » duc van, luc van, thuc van
xuc ban » duc ban, cuc ban, quoc ban
hanh di » hanh vi, hanh de, hang di
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky
va cam » va cham, va cac, va cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky lang xa hoi. lieu va cam ((xuc van) or (xuc ban)) hanh di ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky lang xa hoi. lieu va cam ((xuc van) OR (xuc ban)) hanh di ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky lang xa hoi. lieu va cam ((xuc van) or (xuc ban)) hanh di ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: tu san ky lang xa hoi. lieu va cam ((xuc van) or (xuc ban)) hanh di ((cua triet) OR (su triet))*.
