Perhaps you should try some spelling variations:
cham xuc » chat xuc, cham soc, pham duc
van hanh » van thanh, ban hanh, van anh
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
hanh di » hanh vi, hanh de, hang di
cuu tre » cua tre, cau tren, cau treo
y lang » o lang, tay lang, yen lang
_ lang » o lang, _ land
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) OR (_ lang)) xa 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) OR (_ lang)) xa 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) OR (_ lang)) xa hoi. hieu ve ((cham xuc) or (cam xuc)) van hanh di cuu tre*.
