Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
cau tren » cu tren, dau tren, ca tren
hieu van » hieu va, thien van, lieu va
thanh va » thanh van, hanh va, thanh ha
cham xuc » cam xuc, chat xuc, pham duc
so sach » so sanh, bo sach, co sach
su sach » vu sach
va cau » van cau, va cac, va dau
x hoi » xa hoi, o hoi, x ho

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: ((su sach) OR (so sach)) ky nang x hoi. hieu van ((cham xuc) OR (cham soc)) van thanh va cau tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ky nang x hoi. hieu van ((cham xuc) or (cham soc)) van thanh va cau tren~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) ky nang x hoi. hieu van ((cham xuc) or (cham soc)) van thanh va cau tren*.
