Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cap nguoi » ca nguoi, gap nguoi, giap nguoi
nguoi san » nguoi tay, nguoi dao, nguoi ma
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
hanh de » hanh kem
hanh ve » hanh vi, hanh va, hanh kem
cua tre » cua te, cuu tre, dua tren
ve cap » ve cac, le cap, ve cai
sac ky » cac ky, sai ky
su sac » su sach, su cac, su xac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky nang xa hoi. hieu ve cap nguoi san ((hanh de) or (hanh ve)) ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ve cap nguoi san ((hanh de) OR (hanh ve)) ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ve cap nguoi san ((hanh de) or (hanh ve)) ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu ve cap nguoi san ((hanh de) or (hanh ve)) ((cua tre) OR (cua triet))*.
