Perhaps you should try some spelling variations:
gap nguoi » gian nguoi, dao nguoi, tay nguoi
san thanh » ban thanh, van thanh, son thanh
cap nguoi » ca nguoi, giap nguoi, cua nguoi
san hanh » ban hanh, van hanh, dan hanh
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
xac ky » cac ky, sac ky, bac ky
de cua » le cua, te cua, dieu cua
su xac » pu xac, su cac

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

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