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 » vu sach
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
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
so sach » so sanh, bo sach, co sach

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) OR (so sach)) ky dang 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) OR (so sach)) ky dang xa hoi. ((hieu ve) or (hieu va)) cam xuc ban manh hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) ky dang xa hoi. ((hieu ve) or (hieu va)) cam xuc ban manh hai cua tre*.
