Perhaps you should try some spelling variations:
kham soc » cham soc, kham cuoc, ham so
viet cua » viec cua, viet ca, viet qua
hieu vu » hieu va, hieu ve, dieu vu
hieu su » hieu sau, tieu su, hieu so
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 cu
x hoi » xa hoi, o hoi, x ho

You may be able to get more results by adjusting your search query.

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