Perhaps you should try some spelling variations:
tran thanh » van thanh, quan thanh
ban thanh » ban hanh, ban hang
thien van » thi van
tu sach » thu sach, su sach, te sach
van cua » vang cua, ban cua, dan cua
bao luc » bao thuc
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
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 y nang x hoi. ((hieu ve) or (thien van)) bao luc ((tran thanh) OR (ban thanh)) van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x hoi. ((hieu ve) OR (thien van)) bao luc ((tran thanh) OR (ban thanh)) van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. ((hieu ve) or (thien van)) bao luc ((tran thanh) OR (ban thanh)) van cua tre*".
