Perhaps you should try some spelling variations:
loai nguoi » loi nguoi, hoa nguoi, doi nguoi
moi nguoi » con nguoi, toc nguoi, hoa nguoi
hanh di » hanh vi, hanh de, hang di
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cua tre » cuu tre, cua triet, dua tren
ma hanh » va hanh, da hanh, na hanh
su sac » su sach, su cac, su xac
cua te » cua tu
sac ky » cac ky, sai ky

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 ((loai nguoi) OR (moi nguoi)) ma hanh di ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ve ((loai nguoi) OR (moi nguoi)) ma hanh di ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ve ((loai nguoi) OR (moi nguoi)) ma hanh di ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu ve ((loai nguoi) OR (moi nguoi)) ma hanh di ((cua tre) or (cua te))*.
