Perhaps you should try some spelling variations:
nguoi san » nguoi tay, nguoi dao, nguoi ma
san hang » san chang, ban hang, van hang
nang xa » nang x, lang xa, nang ma
hang di » hang doi, hang vi, hang dien
cua tre » cuu tre, cua triet, dua tren
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
cua te » cua tu

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 thuc) OR (va thuc)) nguoi san hang 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 thuc) OR (va thuc)) nguoi san hang 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 thuc) OR (va thuc)) nguoi san hang di ((cua tre) or (cua te))*".
