Perhaps you should try some spelling variations:
chay tui » chay tu, chay dua, cay tai
co sach » bo sach, cuon sach, hoc sach
xang xa » lang xa, mang xa, ang xa
cay tuc » cay thuc, cay thuoc, day thuc
so sanh » do sanh
cua tre » cua te, cuu tre, cua triet
va dao » ca dao
dao vi » dao voi, dao ve, dao va
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((co sach) OR (so sanh)) ty xang xa hoi. lieu va ((cay tuc) OR (chay tui)) va dao vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((co sach) or (so sanh)) ty xang xa hoi. lieu va ((cay tuc) OR (chay tui)) va dao vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((co sach) or (so sanh)) ty xang xa hoi. lieu va ((cay tuc) OR (chay tui)) va dao vi cua tre*.
