Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
va thanh » gia thanh, ban thanh, va tinh
sach ky » sac ky, sach y, sach kem
dai cuu » dai cua, dai huu
thuc va » thuc vat, thuc dan, thuc day
va tham » van tham, va cham, va thuat
nang xa » nang x, lang xa, nang ma
sach ty » sach y, sach tu, sach thu
cuu tre » cua tre, cau tren, cau treo
va cao » va cac, va co, va dao

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) OR (sach ty)) nang xa hoi. hieu ((va tham) or (va cao)) thuc va thanh dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ky) OR (sach ty)) nang xa hoi. hieu ((va tham) OR (va cao)) thuc va thanh dai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) OR (sach ty)) nang xa hoi. hieu ((va tham) or (va cao)) thuc va thanh dai cuu tre*".
