Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
qua cam » qua cham, qua cac, qua ca
xuc van » duc van, luc van, vuc van
hanh ve » hanh vi, hanh va, hanh kem
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, 5 hoi

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) OR (x ho)). hieu qua cam xuc van ((thanh vi) OR (hanh ve)) cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky nang ((x hoi) OR (x ho)). hieu qua cam xuc van ((thanh vi) or (hanh ve)) cua te~".
• Adding a wildcard symbol may retrieve word variants: tu can ky nang ((x hoi) OR (x ho)). hieu qua cam xuc van ((thanh vi) or (hanh ve)) cua te*.
