Perhaps you should try some spelling variations:
qua cam » qua cham, qua cac, qua ca
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
hanh di » hanh de, hang di, danh di
tu can » tu ban, tu cac, thu canh
can ky » van ky, dan ky, ban ky
cua te » cua tu
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 can ky nang x hoi. hieu qua cam ((xuc van) OR (duc van)) ((hanh di) OR (hanh vi)) cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky nang x hoi. hieu qua cam ((xuc van) OR (duc van)) ((hanh di) or (hanh vi)) cua te~".
• Adding a wildcard symbol may retrieve word variants: tu can ky nang x hoi. hieu qua cam ((xuc van) OR (duc van)) ((hanh di) or (hanh vi)) cua te*.
