Perhaps you should try some spelling variations:
manh hai » lanh hai, minh hai, thanh hai
ban manh » ban hanh, van manh, ban mach
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
hai cua » thai cua, dai cua, hoi cua
xuc ban » duc ban, cuc ban, quoc ban
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu van
ky dang » ky nang, ky danh
ha hoi » hoa hoi, ha noi, va hoi

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 sach ky dang ((ha hoi) OR (xa hoi)). ((hieu ve) OR (hieu va)) cam xuc ban manh hai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang ((ha hoi) OR (xa hoi)). ((hieu ve) or (hieu va)) cam xuc ban manh hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: su sach ky dang ((ha hoi) OR (xa hoi)). ((hieu ve) or (hieu va)) cam xuc ban manh hai cua tre*.
