Perhaps you should try some spelling variations:
cap nguoi » ca nguoi, gap nguoi, giap nguoi
nguoi ban » nguoi san, nguoi dan, nguoi ba
ban hang » ngan hang
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
hang di » hang doi, hang vi, hang dien
cua tre » cuu tre, cua triet, dua tren
su sac » su sach, su xac
su cac » tu cac, su cao, su can
ve cap » ve cac, le cap, ve cai
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) or (su cac)) ky nang xa hoi. hieu ve cap nguoi ban hang di ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cac)) ky nang xa hoi. hieu ve cap nguoi ban hang di ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su cac)) ky nang xa hoi. hieu ve cap nguoi ban hang di ((cua tre) OR (cua te))*".
