Perhaps you should try some spelling variations:
qua cai » qua hai, qua cac, qua ca
cai xuc » cam xuc, chat xuc
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
vai cua » dai cua, hai cua, lai cua
cua tuc » cua duc, cua tu, cua thuoc
su dan » su dang, cu dan, so dan
dan ky » van ky
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: su dan ky nang x hoi. hieu qua cai xuc ((va hanh) OR (va danh)) vai cua tuc~.
• Adding a wildcard symbol may retrieve word variants: su dan ky nang x hoi. hieu qua cai xuc ((va hanh) or (va danh)) vai cua tuc*.
