Perhaps you should try some spelling variations:
cua triet » su triet, va triet
hieu van » hieu va, thien van, lieu va
cau thuc » cau truc, cuu thuc, can thuc
vat hanh » vat thanh, van hanh, va hanh
hanh vai » hanh vi, hanh va, hanh tai
cua viet » ca viet, hoa viet, cua vat
nang xa » nang x, lang xa, nang ma
van cau » van dau, van hau, van chat
su cac » tu cac, su cao, su can

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac ky nang xa hoi. hieu van cau thuc vat hanh vai ((cua triet) OR (cua viet))~".
• Adding a wildcard symbol may retrieve word variants: su cac ky nang xa hoi. hieu van cau thuc vat hanh vai ((cua triet) OR (cua viet))*.
