Perhaps you should try some spelling variations:
dao nguoi » cho nguoi
dang hanh » dang thanh, ban hanh, dang van
gap nguoi » gian nguoi, tay nguoi, lam nguoi
dao hanh » dao thanh, ban hanh, dao van
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
de cua » le cua, te cua, dieu cua
su sac » su sach, su cac, su xac

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

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