Perhaps you should try some spelling variations:
hanh cham » thanh cham, thanh pham, khanh pham
toc sach » hoc sach, doc sach, thuoc sach
thi hanh » thi thanh
cham duc » pham duc, cham soc, pham duy
va thanh » gia thanh, ban thanh, le thanh
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
va tinh » may tinh
cua tre » cua te, cuu tre, cua triet
cu tre » cu tren, cuu tre, cu tri

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

• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ky nang xa hoi. thi hanh cham duc ((va thanh) OR (va tinh)) dinh ((cu tre) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ky nang xa hoi. thi hanh cham duc ((va thanh) OR (va tinh)) dinh ((cu tre) OR (cua tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky nang xa hoi. thi hanh cham duc ((va thanh) OR (va tinh)) dinh ((cu tre) or (cua tre))*".
