Perhaps you should try some spelling variations:
tu cham » toc cham, thi cham
hanh va » hang va, hanh vi
sac van » cac van, san van, sat van
chu tre » cho tre, chu tri, cuu tre
vu cham » va cham, vu kham, qua cham
nang xa » nang x, lang xa, nang ma
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 nang xa hoi. hieu ((vu cham) OR (tu cham)) sac van ((anh va) OR (hanh va)) chu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ((vu cham) or (tu cham)) sac van ((anh va) OR (hanh va)) chu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ((vu cham) or (tu cham)) sac van ((anh va) OR (hanh va)) chu tre*.
