Perhaps you should try some spelling variations:
thanh phan » thanh pho, thanh san, thanh toan
van thanh » ban thanh, van tuan
hieu van » hieu va, thien van, lieu va
cham xuc » cam xuc, chat xuc, pham duc
phan cu » phan cau, phan tu, phan co
tu sach » thu sach, su sach, te sach
cu tren » tu tren, dua tren
sach ky » sac ky, sach y, sach ty
o hai » co hai, so hai, o lai
o hoi » co hoi, o hoc, o hoa

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: tu sach ky nang ((o hoi) OR (o hai)). hieu van ((cham xuc) OR (cham soc)) van thanh phan cu tren~.
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang ((o hoi) or (o hai)). hieu van ((cham xuc) or (cham soc)) van thanh phan cu tren*.
