Perhaps you should try some spelling variations:
cap nguoi » ca nguoi, gap nguoi, giap nguoi
nguoi ma » nguoi tay, nguoi dao, nguoi moi
hang tai » hang va, dung tai
hang dai » hoang dai, hang dau, hang hai
hieu van » hieu va, thien van, lieu va
cua tre » cua te, cuu tre, cua triet
van cap » van cau, van dap, van ca
nang xa » nang x, lang xa, nang ma
su cac » tu cac, su cao, su can
su sac » su sach, 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) or (su cac)) ky nang xa hoi. hieu van cap nguoi ma ((hang dai) OR (hang tai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cac)) ky nang xa hoi. hieu van cap nguoi ma ((hang dai) OR (hang tai)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su cac)) ky nang xa hoi. hieu van cap nguoi ma ((hang dai) OR (hang tai)) cua tre*".
