Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
lang van » dang van, tang van, hoang van
cham xuc » chat xuc, cham soc, pham duc
tu sach » thu sach, su sach, te sach
hanh di » hanh vi, hanh de, hang di
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay
cuu tre » cua tre, cau tren, cau treo
di cuu » di cau, di cua, dinh cuu

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 y ((lang xa) OR (lang van)) hoi. hieu ve ((cham xuc) OR (cam xuc)) van hanh di cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((lang xa) OR (lang van)) hoi. hieu ve ((cham xuc) or (cam xuc)) van hanh di cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach y ((lang xa) OR (lang van)) hoi. hieu ve ((cham xuc) or (cam xuc)) van hanh di cuu tre*.
