Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thanh hai » thanh phan, thanh hoa, thanh san
cap nuoc » dat nuoc
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cua tre » cuu tre, cua triet, dua tren
y nang » ky nang, ly nang, v nang
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach y nang xa hoi. hieu va ((cap nuoc) or (cam xuc)) ban thanh hai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y nang xa hoi. hieu va ((cap nuoc) OR (cam xuc)) ban thanh hai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y nang xa hoi. hieu va ((cap nuoc) or (cam xuc)) ban thanh hai ((cua tre) OR (cua te))*".
