Perhaps you should try some spelling variations:
ban hanh » ban hang
ky tang » ky nang, ky dang, kho tang
tang ma » mang may, tang van
ve cham » va cham, ve chat, ve chim
vu cham » va cham, vu kham, tu cham
cua tre » cua te, cuu tre, cua triet
ma hoi » mai hoi, xa hoi, ma hoa
so ban » sao ban, so bang, co ban
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

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