Perhaps you should try some spelling variations:
hanh hoi » hanh thoi, hanh noi, hanh hoa
ban hanh » ban hang
cua tre » cua te, cuu tre, cua triet
va cham » va chat, va tham
tang xa » trang xa, tang ma, lang xa
hoi cua » hoi chuc
duc ban » duc tan, duc van, dua ban
ky tang » ky nang, ky dang, kho tang
su cac » tu cac, su cao, su can
ve cac » va cac, vien cac
ve cam » ve cham, va cam, ve cai

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