Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
sach ty » sach y, sach tu, sach thu
cao duc » dao duc, cao suc, giao duc
cua tre » cuu tre, cua triet, dua tren
xang x » nang x
va cao » va cac, va co, va dao
cua te » cua tu
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 ty xang x hoi. lieu va cao duc va thanh vai ((((cua tre) OR (cua te))) or (cua vat))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty xang x hoi. lieu va cao duc va thanh vai ((((cua tre) OR (cua te))) OR (cua vat)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty xang x hoi. lieu va cao duc va thanh vai ((((cua tre) OR (cua te))) or (cua vat))".
• Adding a wildcard symbol may retrieve word variants: te sach ty xang x hoi. lieu va cao duc va thanh vai ((((cua tre) OR (cua te))) or (cua vat))*.
