Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, pham duc
cua tre » cua te, cuu tre, cua triet
cao hoi » cau hoi, co hoi, cao hoc
hieu ve » hieu va, hieu van
hang di » hang doi, hang vi, hang dien
hanh di » hanh vi, hanh de, danh di
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky

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 sac ky nang cao hoi. hieu ve ((cham xuc) OR (cham soc)) ban ((hanh di) OR (hang di)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang cao hoi. hieu ve ((cham xuc) or (cham soc)) ban ((hanh di) OR (hang di)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang cao hoi. hieu ve ((cham xuc) or (cham soc)) ban ((hanh di) OR (hang di)) cua tre*.
