Perhaps you should try some spelling variations:
kham soc » cham soc, kham cuoc, ham so
hieu vu » hieu ve, hieu su, dieu vu
hieu va » lieu va, hieu qua
soc van » hoc van, oc van, sac van
van anh » van thanh, tuan anh, van minh
tu sac » tu sach, tu cac, tu san
sac ky » cac 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 nang x hoi. ((hieu vu) OR (hieu va)) kham 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 nang x hoi. ((hieu vu) OR (hieu va)) kham soc van anh viet ((cua tu) or (cua cu))~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang x hoi. ((hieu vu) OR (hieu va)) kham soc van anh viet ((cua tu) or (cua cu))*.
