Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
va thanh » gia thanh, va tinh, le thanh
te sach » toc sach
cac dac » cac dan, cac dai, cac bac
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
y nang » ky nang, ly nang, v nang
x hoi » xa hoi, o hoi, x ho

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 y nang x hoi. lieu va cac dac ((va thanh) or (ban thanh)) dai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. lieu va cac dac ((va thanh) OR (ban thanh)) dai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. lieu va cac dac ((va thanh) or (ban thanh)) dai ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. lieu va cac dac ((va thanh) or (ban thanh)) dai ((cua tre) OR (cuu tre))*.
