Perhaps you should try some spelling variations:
va triet » va thiet, va trien, ve triet
nang doi » nang doc, hang doi, nang dong
nang noi » nang doc
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve 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: tu sac ky lang xa hoi. hieu ((ve cac) OR (va cac)) tuc xa ((nang doi) or (nang noi)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. hieu ((ve cac) OR (va cac)) tuc xa ((nang doi) OR (nang noi)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu ((ve cac) OR (va cac)) tuc xa ((nang doi) or (nang noi)) va triet".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu ((ve cac) OR (va cac)) tuc xa ((nang doi) or (nang noi)) va triet*.
