va thanh » gia thanh, ban thanh, va tinh
hoi cua » hoi chuc
sach ty » sach tu, sach thu, xach tay
cua tre » cua te, cuu tre, cua triet
va dao » ca dao
xang x » nang x
va cao » va cac, va co, va bao
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: tu ((sach ty) or (sach y)) xang x hoi. lieu ((va cao) OR (va dao)) duc va thanh hoi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) xang x hoi. lieu ((va cao) OR (va dao)) duc va thanh hoi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach y)) xang x hoi. lieu ((va cao) OR (va dao)) duc va thanh hoi cua tre*".
