Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
va cham » va chat, va tham
truc va » thuc va, thuc vat, trung va
cua tre » cua te, cuu tre, cua triet
sach ty » sach y, sach tu, sach thu
lang xa » lang ha, dang xay, lang van
ty lang » tay lang, ty xang, ty hang
va cao » va cac, va co, va dao
va cam » va cac, va cai, va cau

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 ty lang xa hoi. hieu ((((va cam) OR (va cham))) or (va cao)) truc va thanh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty lang xa hoi. hieu ((((va cam) OR (va cham))) OR (va cao)) truc va thanh dai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty lang xa hoi. hieu ((((va cam) OR (va cham))) or (va cao)) truc va thanh dai cua tre*".
