Perhaps you should try some spelling variations:
ban hanh » ban hang
hanh hai » thanh hai, nhanh hai, hang hai
cham duc » pham duc, cham soc, pham duy
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va
cua tre » cuu tre, cua triet, dua tren
duc ban » duc tan, duc van, dua ban
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
cua te » cua tu

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: su sac ky lang xa hoi. ((hieu va) OR (hieu qua)) cham duc ban hanh hai ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky lang xa hoi. ((hieu va) OR (hieu qua)) cham duc ban hanh hai ((cua tre) or (cua te))~".
• Adding a wildcard symbol may retrieve word variants: su sac ky lang xa hoi. ((hieu va) OR (hieu qua)) cham duc ban hanh hai ((cua tre) or (cua te))*.
