Perhaps you should try some spelling variations:
nhan luc » nang luc
van hanh » van thanh, ban hanh, van ban
nang xa » nang x, lang xa, nang ma
hieu ca » hieu cac, hieu cua, hieu va
van anh » van thanh, tuan anh, van minh
kem cua » em cua, keo cua, diem cua
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky

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: te ((sac ky) OR (sai ky)) nang xa hoi. hieu ca nhan luc ((van hanh) OR (van anh)) kem cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) OR (sai ky)) nang xa hoi. hieu ca nhan luc ((van hanh) or (van anh)) kem cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) OR (sai ky)) nang xa hoi. hieu ca nhan luc ((van hanh) or (van anh)) kem cua tre*.
