Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
soc van » oc van, sac van, soc dan
hoc van » hoc dan, hoc va, hoc vat
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cau » ke cau, ve cac, le cau
va cau » van cau, va cac, va dau

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 nang xa hoi. hieu vu cham ((soc van) OR (hoc van)) anh ((ve cau) OR (va cau)) treo~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu vu cham ((soc van) or (hoc van)) anh ((ve cau) OR (va cau)) treo~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu vu cham ((soc van) or (hoc van)) anh ((ve cau) OR (va cau)) treo*.
