Perhaps you should try some spelling variations:
dung sai » dung tai, dung va, dung dat
ve triet » va trien, su triet
sach ky » sach y, sach ty, sach kem
lang xa » lang ha, dang xay, lang van
xuc xay » tuc xay, xuc hay, xuat xay
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
cua tu » cua tuc, cua su, cua cu

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

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