Perhaps you should try some spelling variations:
minh hai » minh khai, tinh hai, manh hai
sach vay » sach va, sach nay, sach dao
va trien » va truyen, va thiet, va tuyen
sach hay » sach han, sach ha, sach nay
lang xa » lang ha, dang xay, lang van
va minh » van minh, vua minh, va kinh
va cao » va cac, va co, va dao
xuc va » duc va, tuc va, luc va
hai va » hai van, thai va, hoi va
ve cac » va cac, vien cac

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: thuoc ((sach vay) OR (sach hay)) lang xa hoi. hieu ((ve cac) OR (va cao)) xuc va minh hai va trien~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc ((sach vay) OR (sach hay)) lang xa hoi. hieu ((ve cac) or (va cao)) xuc va minh hai va trien~".
• Adding a wildcard symbol may retrieve word variants: thuoc ((sach vay) OR (sach hay)) lang xa hoi. hieu ((ve cac) or (va cao)) xuc va minh hai va trien*.
