Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van ban
qua cam » qua cham, qua cac, qua ca
van anh » van thanh, tuan anh, van minh
su can » su van, su cao, tu can
can ky » van ky, dan ky, ban ky
vi cua » vai cua, di cua
cua te » cua tu
x hoi » o hoi, x ho, 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: su can ky nang ((x hoi) OR (xa hoi)). hieu qua cam xuc ((van hanh) OR (van anh)) vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su can ky nang ((x hoi) OR (xa hoi)). hieu qua cam xuc ((van hanh) or (van anh)) vi cua te~".
• Adding a wildcard symbol may retrieve word variants: su can ky nang ((x hoi) OR (xa hoi)). hieu qua cam xuc ((van hanh) or (van anh)) vi cua te*.
