Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, pham duc
ban hanh » ban hang
cao hoi » cau hoi, co hoi, cao hoc
hieu ve » hieu va, hieu van
doi cua » dai cua, hoi cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
di cua » dai cua, de cua, do cua

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 cua) OR (doi 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 cua) OR (doi 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 cua) OR (doi cua)) tre*.
