Perhaps you should try some spelling variations:
kham xuc » kham xung, kham cuoc, cam xuc
day cua » dai cua
sach ky » sac ky, sach y, sach kem
hieu vu » hieu va, hieu ve, hieu su
vu kham » vu khanh
nang xa » nang x, lang xa, nang ma
sach ty » sach y, sach tu, sach thu
cua tre » cua te, cuu tre, cua triet
va dap » va dao, va dau
va da » va dao, va dau, va dai

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

• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) or (sach ty)) nang xa hoi. hieu vu kham xuc ((va da) OR (va dap)) day cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach ty)) nang xa hoi. hieu vu kham xuc ((va da) OR (va dap)) day cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach ty)) nang xa hoi. hieu vu kham xuc ((va da) OR (va dap)) day cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach ty)) nang xa hoi. hieu vu kham xuc ((va da) OR (va dap)) day cua tre*.
