Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
van cac » van cau, van bac, dan cac
van hac » van hoc, van ha, van hai
truc va » thuc va, thuc vat, trung va
va hanh » van hanh, va thanh, va danh
vai cua » dai cua, hai cua, bai cua
lai cua » dai cua, hai cua, lai chau
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky

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 sac ky nang xa hoi. hieu ((van cac) OR (van hac)) truc va hanh ((vai cua) OR (lai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ((van cac) OR (van hac)) truc va hanh ((vai cua) or (lai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu ((van cac) OR (van hac)) truc va hanh ((vai cua) or (lai cua)) tre*.
