Perhaps you should try some spelling variations:
ban hanh » ban hang
cham xuc » cam xuc, chat xuc, cham soc
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
xuc ban » duc ban, cuc ban, quoc ban
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
sang ma » tang ma, nang ma, sang tao
ky sang » ky nang, ky dang, ky tang
ma hoi » mai hoi, xa hoi, ma hoa
tu san » thu san, tu ban, tu can
tu sac » tu sach, tu cac, tu bac

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