Perhaps you should try some spelling variations:
vu khac » vu kham, vu khanh, bui khac
khac ty » khac thi
cam tuc » cam xuc, cam tu, nam thuc
ty ang » ty xang, ty hang, ty anh
ang xa » lang xa, mang xa, dang xay
va cam » va cham, va cac, va cao
cua tu » cua tuc, cua su, cua te
cua cu » cua chu, cua cau, cua su

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: vu khac ty ang xa hoi. lieu va cam tuc ((va tinh) OR (may tinh)) vi ((cua tu) OR (cua cu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khac ty ang xa hoi. lieu va cam tuc ((va tinh) OR (may tinh)) vi ((cua tu) or (cua cu))~".
• Adding a wildcard symbol may retrieve word variants: vu khac ty ang xa hoi. lieu va cam tuc ((va tinh) OR (may tinh)) vi ((cua tu) or (cua cu))*.
