Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
van hanh » van thanh, ban hanh, van anh
su sach » so sach
vu sach » vu bach, vu khach
nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
van han » van phan, van nhan, van hoan
thiet » thieu

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 sach) OR (vu sach)) ky nang xa hoi. hieu vu cham xuc ((van han) OR (van hanh)) mai va thiet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ky nang xa hoi. hieu vu cham xuc ((van han) or (van hanh)) mai va thiet~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) ky nang xa hoi. hieu vu cham xuc ((van han) or (van hanh)) mai va thiet*.
