Perhaps you should try some spelling variations:
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
soc van » hoc van, oc van, sac van
van anh » van thanh, tuan anh, van minh
sac ky » sai ky
cua tu » cua tuc, cua su, cua te
cua cu » cua chu, cua cau, cua su
x hoi » xa hoi, o hoi, x ho

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) OR (cac ky)) nang x hoi. hieu vu cham soc van anh viet ((cua tu) OR (cua cu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (cac ky)) nang x hoi. hieu vu cham soc van anh viet ((cua tu) or (cua cu))~".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) OR (cac ky)) nang x hoi. hieu vu cham soc van anh viet ((cua tu) or (cua cu))*.
