Perhaps you should try some spelling variations:
su triet » su viet, ve triet
hieu van » hieu va, thien van, lieu va
nam thuc » nam thuoc, am thuc, nam thu
su tien » su kien, su hien, tu tieng
van anh » van thanh, tuan anh, van minh
va hanh » van hanh, va thanh, va danh
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
sac ky » cac ky, sai ky
tu sac » tu sach, tu cac, tu san

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 sac ky lang xa hoi. hieu van nam thuc ((va hanh) OR (van anh)) vi ((su triet) OR (su tien))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu van nam thuc ((va hanh) or (van anh)) vi ((su triet) OR (su tien))~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu van nam thuc ((va hanh) or (van anh)) vi ((su triet) OR (su tien))*.
